310HBS-3000 Type Digital Display Brinell Hardness Tester
1. Profile
Brinell hardness tester is the largest kind experiment method in all hardness testing. It can reflect comprehensive performance of material, not affected by microscopic segregation and composition of non-uniform of sample organization. So it is a kind of precision of hardness testing method. It is used widely in metallurgy, forging, casting, without hardened steel and non-ferrous metals industry, in laboratory, colleges, and research institutes.
2. Main features
XHB - 3000 type digital display brinell hardness machine is precision mechanical structure and computer control closed-loop system integration of photographic, mechanic and electric products, also is the world's advanced brinell hardness tester. The instrument cancelled weight and used electric load test force; add by 0.5 per 1,000 precision pressure sensors for feedback. CPU control and compensation for the loss of test force. Creasing can be measured in the apparatus through micro-distance measuring eyepiece and can show creasing diameter, hardness value and seventeen different hardness testing the CRT and current setting state automatically displayed brinell hardness test (HBW) range in LCD screen. On a page it can also perform credit lotus time, lamp brightness Settings. At the same time we design a F/D2 selection table for the convenience of usage of users. With RS232 serial instrument into the PC terminal display, print and storage function.
