HRS-150 Digital Rockwell Hardness TesterDetailed product description：

The HRS-150 digital Rockwell hardness tester is an electromechanical integrated hardness testing instrument. The machine has a novel appearance and is controlled by a microcomputer. The hardness value is displayed directly in numbers. The automatic feedback locking between the lifting screw and the rotary wheel, coupled with an external printer, fully realizes automation except for the lifting of the test bench, eliminating operation and reading errors.

This hardness tester is suitable for measuring the hardness of ferrous, non-ferrous, and non-metallic materials.
