Portable hardness tester, STM32, High-precision.


Hardness measurement is a very important index in the process of production and quality inspection. In the past, the precision of portable hardness tester is low, and the stability is poor. Combined with the internal high-speed ADC of the STM32 hardness tester can achieve a more demanding test accuracy requirements. Low power consumption, high accuracy and reliability of data acquisition is realized. And designed with the stemwin library can do more perfect function, human-computer interaction interface is more friendly.
