Very often a person comes to the idea that you need to monitor your health. One of the most important indicators of the fact that a person is in trouble (for example, in the form of a stroke or heart attack) is overweight. In order to constantly monitor this characteristic of your body, you need to have a floor balance at hand. To date, the market of household appliances is represented by two main varieties: household floor mechanical scales and electronic floor scales.
Mechanical floor scales
The principle of operation of mechanical scales is that the spring of the scale is stretched and under its action the arrow or the dial itself rotates. How to adjust the mechanical balance? Yes, it's very simple. This can be done with a special wheel on the end of the device. They show the body weight with an accuracy of 0.5 to 1 kg. As a rule, the maximum weight is limited to 150 kg. Naturally, the error of mechanical weights is slightly larger than that of electronic scales. At the same time, the simplicity of caring for them can be considered a significant plus of mechanical scales.
How to choose a mechanical floor scales?
When choosing a mechanical floor scales, pay attention to how stable they are, and whether the device contains a structure that allows them to be leveled on an uneven floor. Naturally, you should not save on the body of the scales. It is better to immediately buy the scales in a reliable metal case than to worry after the cracked plastic. It is desirable that the surface of the mechanical balance be corrugated or rough. This will prevent your slipping on them in case you want to weigh yourself after the shower and stand on the scales with wet feet. It would be nice to check the accuracy of measuring weights before buying. To do this, you need to know your exact weight or bring something with you whose weight you know for sure (for example, a kilogram of packaged sugar). When checking the accuracy of mechanical scales, you need to press strongly on them and then release them sharply. At this point, the balance arrow should quickly return to the zero mark. If you have visual problems, it is best to buy a mechanical balance with a dial, the numbers are large and painted with red paint.
Electronic balance
This is a much more complicated device. Unlike mechanical scales, the readings are displayed on a monochrome display. The principle is based on the functioning of the voltage sensor. It looks like a wire that begins to stretch, changes the voltage that is applied to it. Then the value of the sensor is interpreted by the electronic filling of the balance and ultimately shows the mass of the body. The division of the weights varies from 0.1 to 0.5 kg. To operate the balance, a battery of 1.5 or 9 volts is usually used. In the most advanced models, work is provided by the energy of the sun or by the principle of the transfer of energy created by the mechanical action of a person to electricity (such an instrument does not need an extra battery). The device is switched on automatically (when the host of the balance becomes on them) or with a separate button. The error in weighing varies from 100 to 1000 g. The maximum load (depending on the manufacturer and the cost) varies from 100 to 220 kg.
Another parameter of this type of scale is the amount of memory (the device is capable of storing several measurements, as well as the values of several users of the balance). Thanks to electronics, a large number of different possibilities are available to users of scales: the calculation of the body mass index ; function of calculating the ratio of the mass of fat and muscle tissue (very approximately, with a large margin of error); the ability to give a beep if there are significant changes in your weight; The presence of a separate display, produced using wireless technologies.
What are all the same scales, electronic or mechanical, buy yourself for home use?
The disadvantages of mechanical floor scales include such facts as:
- Low accuracy of measurements (this type shows mass with accuracy to kilograms);
- No possibility of memorizing results with the device.
Advantages are as follows:
- A much lower price (if compared with the electronic option);
- No need for batteries;
- Easy setup;
- A significant period of operation (the simpler the device, it is durable).
Electronic home scales will please you:
- Absence of necessity, every time you want to weigh, set the balance to the zero mark of the measurement (this happens automatically);
- Low error (in expensive models, weighing is available with an accuracy of 100 g.);
- Suitable even the most dimensional members of your family (maximum weight can reach 220 kg.);
- The availability of the ability to fix your weight in the dynamics.
Disappointment in them can only need to replace the battery (usually no more than 1 time per year).
