The choice between electronic and mechanical scales is basically a choice between accuracy and low cost. Over time, more and more consumers prefer more modern and convenient electronic scales: many models are equipped with so many functions that overpayment seems justified. But some users do not need all these functions, and gram accuracy is also optional, their choice is mechanical models.
Instructions
Step 1
The principle of operation of mechanical scales is simple: a spring is located under the platform, when a person stands on them, it compresses, the pressure makes the arrow move along the scale. No batteries, accumulators, chargers are needed - mechanical scales work in any conditions and are durable if made with high quality. The simplicity of the design also affects the price: most mechanical models are several times cheaper than electronic scales, and this is their main advantage.
Step 2
And the main disadvantage of mechanical scales is inaccuracy. Some devices give an error of up to 2 kg, which does not suit most modern users at all. Although this is an extreme, many modern models are mistaken by a maximum of half a kilogram - some cheap electronic scales have a greater error. In short, if you are satisfied with the readings with a spread of about a kilogram, you should not overpay for an electronic model, but such scales will not work for lovers of accuracy.
Step 3
Electronic balances do offer great accuracy as they work with a special sensor made from a pressure-sensitive material. Information about pressure is converted into electronic form and enters the display, which reflects the weight with tenths, and sometimes hundredths of a kilogram. Losing weight girls, bodybuilders, pregnant women, it is important to know the slightest changes in their body. But you need to understand that neither mechanical nor electronic scales reflect the amount of fat in the body, because changes in weight can be caused by fluctuations in fluid in the body and other reasons.
Step 4
Some electronic scales are equipped with many additional features, including a body fat percentage calculator. But here they do not guarantee accuracy, calculating the weight only approximately, according to standard formulas. Only the most expensive models with special sensors can really estimate the amount of fat, muscle and bone tissue in the body.
Step 5
Electronic scales are more expensive than mechanical ones, but if you do not choose a model with a whole range of additional functions, the overpayment for accuracy will be small and quite justified. Electronic scales run on rechargeable batteries, but the power consumption is so low that they can be used for years without having to remember to replace the batteries. In addition, the choice of electronic models is much wider, and the design is much more attractive.
