Rockwell Hardness Tester LHRMS-45 (Touch Screen)
Brief Introduction
1. Hardness is one of the important mechanic characteristics of the material while the hardness testing is an important method to judge the quality of the metal material or its component parts. The hardness of the metal is correspondent to its mechanic characteristics, and so its mechanic characteristics such as the strength, wriggling and wearing out can be tested out approximately through its hardness testing.
2. The Digital Superficial Rockwell Hardness Tester LHRMS-45 is equipped with a newly-designed large displaying screen with good reliability, excellent operation and easy watching, thus combing in one high-tech product the mechanic and electric features.
2.1 The selection of Superficial Rockwell Hardness Scales;
2.2 Conversion of different Hardness scales;
2.3 The function of printing and automatic storage hardness testing results.
