570HAD Digital Brinell Rockwell&Vickers Hardness Tester
570HAD Digital Brinell Rockwell&Vickers Hardness Tester
Brief introduction of Hardness Testers
Hardness is one of the mostly oftenused mechanics characteristics of the metal material, while the hardness testing is the most quickly and economic testing method, as well as an important method to judge the quality of the metal material or its component parts. The mechanic characteristics of most metal materials such as the strength, tiredness, wriggling and wearing out can be tested out approximately through its hardness testing. The 570HAD Digital Brinell Rockwell & Vickers Hardness Tester with a novel and pleasing appearance, full functions, easy operation, clear and directviewing display and stable performance is a hightech and new product combining the mechanic; electric and optical features. This multifunction hardness tester with Brinell; Rockwell and Vickers 3 testing methods, as well as 7 steps test force can meet the needs of manifold hardness test. The process of loading, dwelling and unloading of test force are shifted automatically, therefore the operation is simply and promptly. Its main function is as follows:
1. With 3 hardness testing methods such as Brinell; Rockwell and Vickers;
2. The hardness values exchange among various hardness scales;
3. The selection of dwell time for hardness test.
4. The revising of the value for year, month and date.
5. The hardness test result can be printed output.
6. The RS232 serial communication is supplied to clients for the functional expansion. The Present hardness tester with the storage function can be browsed the hardness testing
