manually operation analog rockwell hardness tester can get result by reading on analog dial gause, no need electricity supply, wide using range
Working principle of Rockwell hardness test:
The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test determines the hardness by measuring the depth of penetration of an indenter under a large load compared to the penetration made by a preload. There are different scales, denoted by a single letter, that use different loads or indenters. The result is a dimensionless number noted as HRA, where A is the scale letter.
Name: Manually operation analog rockwell hardness tester
1. Easy to operate, analog dial reading directly
2. Outstanding panting technology, long using life
3. One-time casted molding shell, stable structure and it is not easy to be out of shape.
4. Dead weight structure makes high stabilty working status.
