This depends on the principle of the weight scale. At present, most of the common weight scales on the market use the "BIA bioelectrical impedance analysis method", because the tissue structure of different parts of the body, such as muscle and fat, have different electrical conductivity.
Since fat contains almost no water and has extremely poor electrical conductivity, when a person stands on a smart body weight scale with both feet, a microcurrent is generated when the skin contacts the electrodes, and the whole body circulates, thereby obtaining the body fat and fat content of the body.
This is why we need to stand with both feet on the scale designated by the merchant when we use the scale. In this way, the measured microcurrent can be effectively generated.
Is this method accurate for measuring the body? Since we get up in the morning and go to bed at night, the body's conditions are constantly changing, even if it's just one minute and the next minute, the body's electrical conductivity is also different.
Therefore, at present, the body fat rate, muscle rate and other data of all smart body weight scales are only for reference, and if it is measured every day, it is best to fix the time, such as getting up in the morning, such data will be relatively comparable.
If you have the opportunity to test the product, you can wear the same clothes in a short period of time, repeat the measurement 3-5 times, and compare the data each time. If the data difference is not big, it means that this smart body weight scale is relatively stable. If the data is very different each time, you can consider changing it. Try to measure with your feet apart and with your feet together. If the data is close, it means that this Bluetooth scale is not very reliable.
Read more about brand manufacturers' promotions and product descriptions. If a weight scale product claims to be able to measure bone density, bone age and other functions that require professional measurement, you can consider looking at other weight scales. The measurement of bone density, bone age, etc. cannot be measured through bio-resistance technology. This function is obviously exaggerated or even false propaganda.
Whether the APP is easy to use or not is also a matter to be considered. Different Bluetooth scales use different APPs, and whether it is easy to connect, whether it is easy to disconnect, the transmission speed and synchronization between the data measured each time and the mobile APP, and whether the APP is simple and easy to use, whether the records of multiple data are accurate, etc. should be considered when purchasing a scale. After all, all our data records are in the APP for viewing at any time.
In addition, according to the measurement data, whether a relatively high-quality body improvement suggestion can be given is also a different function of each scale. You can learn more about several scales to see if the different suggestions are really effective; and whether this Bluetooth scale supports more The association of various sports APPs can synchronize data, and it can also be considered if it is a person with fitness needs.
Finally, it is necessary to look at the production process of the actual product, and whether there are obvious defects in the product as a whole. Don't blindly trust the brand, but see more and understand more.
When choosing a weight scale, don't be too concerned about how accurate its data is. You must know that the complexity of the body will directly affect the data of each measurement, as long as the data measured multiple times is continuous. Don't pay too much attention to the brand. Although big brands have their own advantages, such as stable quality, there are many factors that need to be considered when purchasing a smart body weight scale. Brand is only one of the factors.
