The lifetime of the sensor is the key.
The sensor life of electronic scale is the key to ensure accuracy. As long as you avoid overload, treat it gently and stay away from humid environment, it can accompany you for a long time.
Life test of kitchen scale
For cost reasons, kitchen scales may use common electronic devices and sensors. Although the resolution is not high, the life test is actually very simple. Just take 2/3 of the cargo range, load and unload at a constant speed, and observe the weighing value at the same time. As long as the error does not exceed plus or minus 3 points, your scale is still healthy.
Minimum weighing and life test instrument
1G is not the minimum weight, but the index value is displayed. The manufacturer also has a professional life test instrument, which can set the loading and unloading times, generally from 1000 to 10000.
