HHR-1Rockwell hardness testing instrument

1Introduction and Application Scope of Rockwell Hardness Sounding Device Calibration Instrument
The HHR-1 Rockwell Hardness Depth Tester is a specialized metrological standard device used for the calibration of Rockwell hardness testing institutions (directly verifying the indication error of the metal Rockwell hardness tester indentation depth measurement device). Its structural performance and technical indicators comply with the requirements of "JJG 112 Verification Regulations for Metal Rockwell Hardness Testers" and "ISO 6508.2 Metallic Materials Rockwell Hardness Test Part 2 Inspection and Calibration of Hardness Testers", making it very suitable for metrology departments and hardness tester manufacturers for the calibration or calibration of hardness testers.

The Rockwell hardness testing device adopts a mechanical electronic integrated structure, and through careful industrial structure design and precise mechanical processing technology, ensures the structural stability and measurement accuracy of the instrument. The electronic part uses precision and high linearity electronic components and a microcontroller data acquisition system, which has software calibration and indication correction functions, ensuring the accuracy and usability of the instrument.
