S3-MHRSS-150/45-Zr - Fully Automatic Rockwell Hardness Tester, adopted the international advanced closed-loop sensor control technology, to achieve full automatic control and hardness testing process. The load system uses high-precision force value sensor and central controller to form a closed-loop loop to achieve full microsecond level tracking and control of the booster process.
The measurement system uses high-precision displacement sensor with a hardness value resolution of 0.1 HR and an accuracy of ± 0.15 HR. The position of the indenter is fixed, and the hardness test is carried out by moving up and down the platform. The overall movement of the large platform eliminates the gap generated during the lifting and lifting of the wire bar, greatly improves the accuracy and repeatability of the test, and also increases the stability and efficiency of the machine's work. Add foot switch function, a key type of measurement, saving a lot of manpower, convenient for use in the field.
