Application:
KASON HTR-150A Manual Metal Rockwell Hardness Tester is an indispensable hardness measuring
instrument in machinery, metallurgy and metrology department. It mainly functions are as follows:
l Lever Loading, manual operation, durable and reliable.
l No friction spindle, high precision Test force.
l Precision hydraulic buffers, steady load.
l Dial display the hardness value, HRA, HRB, HRC, and can choose other Rockwell Scale.
l Accuracy according to GB / T230.2, ISO 6508-2 and American ASTM E18 standard.
Usage Range:
Rockwell hardness measurement of ferrous metals, non-ferrous metals and non-metallic materials.
Wide range of applications, suitable for rockwell Hardness Testing of hardening, quenching and other heat-treated material.
