How to choose electronic floor scales for your home?

The choice of floor electronic scales for the home should be made taking into account such parameters as:

• maximum load - many models of scales can withstand a load weighing 140-200 kg, but the most common option is devices designed for 150 kg. The device cannot be overloaded, so it is better to purchase a model with a small reserve;
• the ability to synchronize with a smartphone - will allow you to save the received data in the application, thanks to which the owner will later be able to analyze the process of building or gaining weight. In this case, some of the data is entered manually, and some is supplemented with current information;
• measurement accuracy - when choosing a unit, it is important to consider that all models have a slight weighing error. In budget models, the error can be up to 0.5 kg, but more expensive devices are distinguished by increased accuracy - the figure approaches only 50 g;
• additional functionality - the presence of all kinds of additional options will significantly simplify the operating process and increase the cost of the equipment. Modern models are often equipped with functions such as determining the percentage of muscle, fat and bone tissue, as well as the proportion of fluid in the body;
• dimensions, weight and design of the electrical device - the device must be equipped with a platform of optimal size so that both the owner with a 35-foot size and a 42-foot size can use the scale, have a light weight and have an attractive appearance. In addition, moving a compact device will be much more convenient;
• body and platform material – the most popular are models made of plastic and tempered glass. Devices made of wood are very pleasant to the touch, but their cost is higher. You can also find cutlery made of stone in display cases – they attract with their naturalness, but have a lot of weight;
• cost - the price range for floor electronic scales is from 500 to 8000 rubles. The cost depends on the popularity of the brand and the availability of additional functions.

Records in science and technology. Limit values

Highest temperature

It was obtained at the center of a thermonuclear bomb explosion - about 300...400 million°C. The maximum temperature reached during a controlled thermonuclear reaction at the TOKAMAK fusion test facility at the Princeton Plasma Physics Laboratory, USA, in June 1986, is 200 million °C.

Lowest temperature

Absolute zero on the Kelvin scale (0 K) corresponds to –273.15° Celsius or –459.67° Fahrenheit. The lowest temperature, 2 10–9 K (two-billionth of a degree) above absolute zero, was achieved in a two-stage nuclear demagnetization cryostat at the Low Temperature Laboratory of the Helsinki University of Technology, Finland, by a team of scientists led by Professor Olli Lounasmaa (b. 1930). ), which was announced in October 1989.

The smallest thermometer

Dr. Frederick Sachs, a biophysicist at the State University of New York, Buffalo, USA, designed a microthermometer to measure the temperature of individual living cells. The diameter of the thermometer tip is 1 micron, i.e. 1/50th the diameter of a human hair.

The largest barometer

The 12 m high water barometer was constructed in 1987 by Bert Bolle, curator of the Barometer Museum in Martensdijk, the Netherlands, where it is installed.

The greatest pressure

As reported in June 1978, the highest continuous pressure of 1.70 megabar (170 GPa) was obtained at the Carnegie Institution Geophysical Laboratory, Washington, USA, in a giant diamond-coated hydraulic press. It was also announced that in this laboratory on March 2, 1979, solid hydrogen was obtained under a pressure of 57 kilobars. Metallic hydrogen is expected to be a silvery-white metal with a density of 1.1 g/cm3. According to calculations by physicists G.K. Mao and P.M. Bella, this experiment at 25°C will require a pressure of 1 megabar.

In the USA, as reported in 1958, using dynamic methods with impact speeds of about 29 thousand km/h, an instantaneous pressure of 75 million atm was obtained. (7 thousand GPa).

Highest speed

In August 1980, it was reported that a plastic disk was accelerated to a speed of 150 km/s at the US Naval Research Laboratory, Washington, USA. This is the maximum speed at which a solid visible object has ever moved.

The most accurate scales

The most accurate scales in the world - "Sartorius-4108" - were manufactured in Göttingen, Germany, they can weigh objects up to 0.5 g with an accuracy of 0.01 mcg, or 0.00000001 g, which corresponds to approximately 1/60 of the weight printing ink wasted on the period at the end of this sentence.

The largest bubble chamber

The world's largest bubble chamber, costing $7 million, was built in October 1973 in Weston, Illinois, USA. It has a diameter of 4.57 m, holds 33 thousand liters of liquid hydrogen at a temperature of –247 ° C and is equipped with a superconducting magnet that creates a field of 3 Tesla.

The fastest centrifuge

The ultracentrifuge was invented by Theodor Svedberg (1884...1971), Sweden, in 1923.

The highest rotation speed achieved by a person is 7250 km/h. At this speed, a 15.2 cm conical carbon fiber rod was reported to be rotating in a vacuum on January 24, 1975, at the University of Birmingham, UK.

The most accurate section

As reported in June 1983, a high-precision diamond lathe at the National Laboratory. Lawrence in Livermore, California, USA, can cut a human hair lengthwise 3 thousand times. The cost of the machine is 13 million dollars.

The most powerful electric current

The most powerful electric current was generated at the Los Alamos Scientific Laboratory, New Mexico, USA. With the simultaneous discharge of 4032 capacitors, combined into the Zeus supercapacitor, within a few microseconds they produce twice the electric current than that generated by all power plants on Earth.

The hottest flame

The hottest flame is produced by the combustion of carbon subnitride (C4N2), which produces at 1 atm. temperature 5261 K.

Highest measured frequency

The highest frequency perceived by the naked eye is the oscillation frequency of yellow-green light, equal to 520.206 808 5 terahertz (1 terahertz - million million hertz), corresponding to the 17 - 1 P(62) transition line of iodine-127.

The highest frequency measured by the instruments is the green light frequency of 582.491703 THz for the b21 component of the R(15) 43 – 0 transition line of iodine-127. The decision of the General Conference of Weights and Measures, adopted on October 20, 1983, for the precise expression of the meter (m) using the speed of light ( c

) it is established that “a meter is the path traveled by light in a vacuum in a time interval equal to 1/299792458 of a second.”
As a result, frequency ( f
) and wavelength (λ) are related by the dependence
f
·λ =
c
.

The weakest friction

Polytetrafluoroethylene (C2F4n), called PTFE, has the lowest coefficient of dynamic and static friction for a solid (0.02). It is equal to the friction of wet ice on wet ice. This substance was first produced in sufficient quantities by the United States in 1943 and was exported from the United States under the name “Teflon.” American and Western European housewives love pots and pans with non-stick Teflon coating.

In a centrifuge at the University of Virginia, USA, a rotor weighing 13.6 kg, supported by a magnetic field, rotates in a vacuum of 10–6 mm Hg at a speed of 1000 rps. It only loses 1 rps per day and will spin for many years.

Smallest hole

A hole with a diameter of 40 angstroms (4 × 10–6 mm) was seen on a JEM 100C electron microscope using a device in the Department of Metallurgy, Oxford University, UK, on ​​October 28, 1979. Finding such a hole is like finding a pinhead in a haystack with sides 1.93 km.

In May 1983, an electron microscope beam at the University of Illinois, USA, accidentally burned a hole 2·10–9 m in diameter in a sample of sodium beta aluminate.

The most powerful laser beams

For the first time, it was possible to illuminate another celestial body with a beam of light on May 9, 1962; then a beam of light was reflected from the surface of the Moon. It was aimed by a laser (a light amplifier based on stimulated emission of radiation) whose sighting precision was coordinated by a 121.9 cm telescope located at the Massachusetts Institute of Technology, Cambridge, Massachusetts, USA. A spot with a diameter of about 6.4 km was illuminated on the lunar surface. The laser was proposed in 1958 by the American Charles Townes (born 1915). A light pulse of similar power with a duration of 1/5000 can burn through a diamond due to its evaporation at temperatures up to 10,000°C. This temperature is created by 2·1023 photons. As reported, the Shiva laser installed in the laboratory named after. Lawrence Livermore, California, USA, was able to concentrate a light beam with a power of about 2.6 × 1013 W on an object the size of a pinhead for 9.5 × 10–11 s. This result was obtained in an experiment on May 18, 1978.

The brightest light

The brightest sources of artificial light are laser pulses, which were generated at Los Alamos National Laboratory, New Mexico, USA, in March 1987 by Dr. Robert Graham. The power of a flash of ultraviolet light lasting 1 picosecond (1·10–12 s) was 5·1015 W.

The most powerful continuous light source is a high pressure argon arc lamp with a power input of 313 kW and a luminous intensity of 1.2 million candelas, manufactured in Vancouver, Canada, in March 1984.

The most powerful searchlight was produced during the Second World War, in 1939...1945. It was developed at the Hearst Research Centre, London. With a power input of 600 kW, it produced an arc brightness of 46,500 cd/cm2 and a maximum beam intensity of 2,700 million cd from a parabolic mirror with a diameter of 3.04 m.

The shortest pulse of light

Charles Shank and colleagues at the laboratories (ATT), New Jersey, USA, received a light pulse with a duration of 8 femtoseconds (8 10–15 s), which was announced in April 1985. The pulse length was 4 ... 5 wavelengths of visible light, or 2.4 microns.

The longest lasting light bulb

The average incandescent light bulb burns for 750 to 1000 hours. It is reported that the five-watt carbon filament lamp, manufactured and recently demonstrated by Mr. Burnell at the Fire Department of Livermore, California, USA, first gave light in 1901.

The heaviest magnet

The largest electromagnet

The world's largest electromagnet is part of the L3 detector used in experiments at the Large Electron-Positron Collider (LEP) of the European Council for Nuclear Research, Switzerland. The octagonal-shaped electromagnet consists of a yoke made of 6400 tons of low-carbon steel and an aluminum coil weighing 1100 tons. The yoke elements, weighing up to 30 tons each, were manufactured in the USSR. The coil, made in Switzerland, consists of 168 turns, electrically welded to an octagonal frame. A current of 30 thousand A passing through an aluminum coil creates a magnetic field with a power of 5 kilogauss. The dimensions of the electromagnet, exceeding the height of a 4-story building, are 12x12x12 m, and the total weight is 7810 tons. More metal was spent on its production than on the construction of the Eiffel Tower.

Magnetic fields

The most powerful constant field of 35.3 ± 0.3 Tesla was obtained at the National Magnetic Laboratory. Francis Bitter at the Massachusetts Institute of Technology, USA, May 26, 1988. To obtain it, a hybrid magnet with holmium poles was used. Under its influence, the magnetic field created by the heart and brain intensified.

The weakest magnetic field was measured in a shielded room in the same laboratory. Its value was 8·10–15 Tesla. It was used by Dr. David Cohen to study the extremely weak magnetic fields produced by the heart and brain.

The most powerful microscope

The Scanning Tunneling Microscope (STM), invented at the IBM Research Laboratory in Zurich in 1981, can achieve a magnification of 100 million times and resolve details down to 0.01 atomic diameters (3 × 10–10 m). It is claimed that the size of the 4th generation scanning tunneling microscopes will not exceed the size of a thimble.

Using field ion microscopy techniques, the probe tips of scanning tunneling microscopes are made so that there is one atom at the end - the last 3 layers of this man-made pyramid consist of 7, 3 and 1 atom. In July 1986, representatives of the Bell Telephone Laboratory Systems, Murray Hill, New Jersey, USA, announced that they were able to transfer a single atom (most likely germanium) from the tungsten probe tip of a scanning tunneling microscope to a germanium surface. In January 1990, a similar operation was repeated by D. Eigler and E. Schweitzer from the IBM Research Center, San Jose, California, USA. Using a scanning tunneling microscope, they laid out the word IBM

single xenon atoms, transferring them to the nickel surface.

The loudest noise

The loudest noise obtained in laboratory conditions was 210 dB, or 400 thousand ac. Watts (acoustic watts), NASA reported. It was obtained by reflecting sound from a 14.63 m reinforced concrete test stand and 18.3 m deep foundation designed for testing the Saturn V rocket at the Space Flight Center. Marshall, Huntsville, Alabama, USA, in October 1965. A sound wave of such strength could drill holes in solid materials. The noise was heard within 161 km.

The smallest microphone

In 1967, Professor Ibrahim Cavrak of Bogazici University, Istanbul, Turkey, created a microphone for a new technique for measuring pressure in a fluid flow. Its frequency range is from 10 Hz to 10 kHz, dimensions are 1.5 mm x 0.7 mm.

Highest note

The highest note received has a frequency of 60 gigahertz. It was generated by a laser beam aimed at a sapphire crystal at the Massachusetts Institute of Technology, USA, in September 1964.

The most powerful particle accelerator

Proton synchrotron with a diameter of 2 km at the National Acceleration Laboratory. Fermi, east of Bateivia, Illinois, USA, is the world's most powerful nuclear particle accelerator. On May 14, 1976, an energy of about 500 GeV (5·1011 electron-volts) was obtained for the first time. On October 13, 1985, as a result of the collision of beams of protons and antiprotons, an energy in the center of mass system of 1.6 GeV (1.6·1011 electron-volts) was obtained. This required 1,000 superconducting magnets operating at a temperature of -268.8°C, maintained using the world's largest helium liquefaction plant with a capacity of 4,500 l/h, which came into operation on April 18, 1980.

CERN's (European Organization for Nuclear Research) goal of colliding beams of protons and antiprotons in the ultra-high energy proton synchrotron (SPS) with an energy of 270 GeV 2 = 540 GeV was achieved in Geneva, Switzerland, at 4:55 a.m. on July 10 1981. This energy is equivalent to that released during the collision of protons with an energy of 150 thousand GeV with a stationary target.

The US Department of Energy on August 16, 1983 subsidized research to create a superconducting supercollider (SSC) with a diameter of 83.6 km by 1995 using the energy of two proton-antiproton beams at 20 TeV. The White House approved this $6 billion project on January 30, 1987.

The quietest place

The 10.67 x 8.5 m "dead room" at the Bell Telephone Systems Laboratory, Murray Hill, New Jersey, USA, is the most sound-absorbing room in the world, in which 99.98% of reflected sound disappears .

The sharpest objects and the smallest tubes

The sharpest human-made objects are the glass micropipette tubes used in experiments with living cell tissue. The technology for their production was developed and implemented by Professor Kenneth T. Brown and Dale J. Flaming at the Department of Physiology at the University of California at San Francisco in 1977. They obtained conical tube tips with an outer diameter of 0.02 μm and an inner diameter of 0.01 μm . The latter was 6500 times thinner than a human hair.

The smallest artificial object

On February 8, 1988, Dallas, Texas, USA, announced that it had succeeded in producing “quantum dots” from indium and gallium arsenide with a diameter of only 100 millionths of a millimeter.

Highest vacuum

It was obtained at the IBM Research Center named after. Thomas J. Watson, Yorktown Heights, New York, USA, in October 1976 in a cryogenic system with temperatures down to –269°C and was equal to 10–14 torr. This is equivalent to the distance between molecules (the size of a tennis ball) increasing from 1 m to 80 km.

Lowest viscosity

The California Institute of Technology, USA, announced on December 1, 1957 that liquid helium-2 at temperatures close to absolute zero (–273.15°C) does not have viscosity, i.e. has ideal fluidity.

Highest voltage

On May 17, 1979, the highest electrical potential difference was obtained under laboratory conditions at National Electrostatics Corporation, Oak Ridge, Tennessee, USA. It amounted to 32 ± 1.5 million V.

Having decided on the need to purchase electronic bathroom scales, you should listen to the recommendations of experts in the field of household appliances and devices for tracking physical health indicators, and also remember a few nuances:

• the main criteria for choosing equipment are the maximum permissible load and functionality - these parameters must be paid attention to first;
• the presence or absence of the ability to synchronize the device with a smartphone should be taken into account - this will allow the received data to be saved in the application, so that in the future the owner will be able to analyze the process of building or gaining weight;
• When choosing a device, special attention should be paid to the material of the body and platform, dimensions and weight - the best option would be a device with a durable plastic platform, suitable in size for those with feet of both size 36 and size 42;
• It would not be a bad idea to ask a consultant about the measurement accuracy of an electrical appliance - the lower the measurement error, the more accurate the result will be;
• the cost of equipment directly depends on its functionality, which is why it is necessary to decide in advance on the desired options and understand for yourself which of the proposed functions are definitely not needed.

Background

A whole group of scientists worked on the creation, since they were faced with a difficult task, namely, to create a device whose error would be close to zero. The best professors at the German Institute of Ilmenau (a small town in Germany) worked on the project for more than five years to eventually show the world scales with the smallest error.

The work began after the International Bureau of Weights and Measures, which maintains the standard kilogram, invited scientists from all over the world to create a unique device. By the way, before this, many institutes and groups of scientists had already tried to create the most accurate scales, but, having spent a lot of time and money, they could not even come close to the accuracy that professors Ilmenau showed.

The main customer of this project is also considered to be a company from Germany - the Sartorius technology concern. The most accurate scales received the same name as the aforementioned technology concern, namely “Sartorius-4108”.

Unique facts and technical characteristics of the scales:

• When weighing a reference kilogram, the designed scales show extremely accurate mass with a minimum error of 100 nanograms.
• If weighing is carried out in a vacuum, then the error of the device will be 50 nanograms.
• These are the first scales that were able to reach the level of error measured in nanograms.
• For representation, this is the weight of typographic ink that is spent on one small dot.
• In addition to the fact that professors from the Institute of Measuring Processes and Sensor Technology Ilmenau managed to construct the most accurate device, it does not lose its properties even after many weighings. Before this, devices were created, but they were enough for no more than 2-10 weighing procedures.
