1.Application:

HR-150A Manual Rockwell Hardness Tester adopts mechanical manual testing, does not require power, 

has a wide range of applications, easy to operate, and has good economy and practicality.

The dial reads the hardness value directly and can be equipped with other Rockwell hardness scales, 

such as HRD, HRF, etc.

HR-150A Manual Rockwell Hardness Tester adopts a precision hydraulic buffer made of the integrated 

casting, there is no buffer leakage, and the loading and unloading are smooth, without impact, and the 

speed is adjustable. The accuracy complies with GB/T230.2-2018, ISO6508-2 and American ASTM E18 

standards.

2.Application Range:

(1).Measure the Rockwell hardness of black metals, non-ferrous metals, and non-metallic materials.

(2).Measurement of Rockwell hardness of heat treated materials such as hard alloys, carburized steel, 

quenched steel, surface quenched steel, hard cast steel, aluminum alloys, copper alloys, malleable 

castings, soft steel, quenched and tempered steel, annealed steel, bearings, etc.
