Electic Twin Rockwell Hardness Tester
Model :HRR-150DT
electic twin rockwell hardness tester has stable and reliable performance ,it can meet the rockwell hardness test
requirements of all metal materials and can effectively avoid the error by manual, it is a economical rockwell machine
all –in-one.
Main function and features :
1. The machine can meet the metal rockwell and superficial rockwell hardness test requirements; high test precision;
good repeatability;
2. Test force load, dwell, and unload is automatic, it is avoid the error by manual;
3. The dial reads the hardness value directly, indicator responses sensitively, show the hardness value accurately,
the test value is more accurate than national standard;
4. One-time casted molding shell, stable structure and it is not easy to be out of shape. It can work under harsh
environment; the shell coating adopted car paint technology with white color. it has strong scratch resistance
capability and still look bright as new after use many years;
5. Factory directly supply, we have products develop &design & produce ability, all the parts provide life-time
replacement and maintenance service.
Main application :
1. Hardened steel, quenched and tempered steel, annealing steel, bearing steel, strip steel, hardened steel sheet,
hard alloy, etc.;
2. Galvanized, chrome plating, tin plating, heat treatment of materials and chemical surface treatment of all kinds of thin
metallic materials.
