1. The specially designed indenter extends horizontally and can measure the annular, tubular and other parts that cannot be measured by ordinary hardness tester. The minimum test inner diameter is 25mm.

2. It adopts electronic and electric loading, high-precision sensor and unique closed-loop control system.

3. Touch screen interface, easy to operate, directly select the hardness scale, and the force value automatically changes in the test parameters.

4. According to the standard hardness block, each hardness scale is automatically corrected in three sections: high, medium and low.

5. The test force can be automatically corrected through the standard dynamometer.

6. Apply the main test force automatically.

7. The data processing function is powerful, including: conversion of HR, HB, HV and other hardness systems, setting of qualified range, automatic alarm for overrun, and input of tester, sample name and other information.

8. For more sample and test information, the measurement data USB flash disk is saved in EXCEL format for easy editing and processing.
