Dial Reading Resolution 0.5HR Manual Operation Rockwell Hardness Tester with Stable Performance
Brief Introduction:
HR-150A Manual Rockwell hardness tester designed with the beautiful appearance and the interface menu, with the stable performance and economic costs, used widely in different applications.
Main Features:
1, The dial reading with resolution 0.5HR, in higher sensitivity.
2, The shell made by the special foundry molding casting, with the stable structure, can work under the rugged environment; with the high class automobile paint with high anti scratch ability.
3, Our R& D team can provide the service for the maintenance and upgrade if necessary.
Application Range:
Chilled Hardened Steel, quenching and tempering steel, annealed steel, bearing steel, strip steel, harden sheet steel, hardness alloy, etc.
● HRC is most applicable to testing carbon steel after quenching or low tempering, alloy steel, tool steel, die steel, as well as chilled cast iron, titanium alloy and so on. Generally, we apply HRC scale to test materials HRB>100, and HRB scale to test materials HRC<20 avoiding influence caused by glide of indenter.

Maintenance and Precautions:
1. Test personnel should follow the operating procedures, can be used before and after the test standard block calibration equipment. Do not often use the hardness, after the boot.Standard block to be several times on the determination of hardness, stability, and then test the specimen.
2. The instrument should be carried at the end of handling, not down, and remove the weight and boom.
3. In the hardness test, add the test force to maintain the test force, remove the test force, is strictly prohibited to turn the variable hand wheel.
4. The use of the hardness of the block can only be carried out in the face, two adjacent indentation and indentation center to edge distance of not less than 3mm, the use of two year.
5. Hardness test cycle to do a good job at least once a year to ensure the accuracy of hardness.
