HRS-150 Digital Rockwell Hardness Tester

Description

Product Introduction:

The HRS-150 digital automatic Rockwell hardness tester features a modern design and a user-friendly menu interface. Its measuring system employs a grating sensor and computer control, with hardness values displayed directly on an LCD screen, making it an electromechanical integrated hardness testing instrument. The device can automatically convert among various hardness scales, determine the minimum specimen thickness, and measure the ambient test temperature. It also includes a built-in printer for recording relevant test results. With fully automated operation, it eliminates human error in handling and reading measurements.

Main uses and scope of application:

Castings and Forgings: Sample Testing and Acceptance Inspection
