Product details
HRM-45Manual surface Rockwell hardness tester
brief introduction
HRM-45A surface Rockwell hardness tester is suitable forThe surface Rockwell hardness of metal materials is measured, and the speed of applying the test force is adjusted by a buffer,Rockwell hardness tester for loading, holding, and unloading tests of metal material surface hardness，It has the characteristics of easy operation, small indentation, high accuracy, etc
u Leverage loading, manual operation, * * durability, high testing efficiency
u Using universal suspension rods (bricks) to achieve free connection between the weight system and the load lever
u Easy to install and low failure rate
u The dial can directly read HEN and HRT scales (other surface Rockwell scales can be optionally selected)
