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.
