Brief Introduction:
1, The degree of hardness is one of material machine capability
important targets, and the hardness test is one of the important
methods about judging the metal material or the components quality.
Because the metal degree of hardness has the mutual corresponding
relations with other machine capability. Therefore, determining the
degree of hardness may approximately calculate the majority metal
material’s other machine capability, such as intensity, weary, slow
change, attrition and so on.
2, An automatic testing pressure loading / unloading mechanism, as
well as a potentiometer for total testing pressure holding time
adjustment, are equipped on LHR-150A Rockwell Hardness Tester, and
the testing pressure change can be obtained by turning of the
load-selection handwheel, making its operation easy and simple. The
tester enjoys high sensitivity and stability, thus is designed for
use in workshops and laboratories.
