HBRV-187.5DX Brinell Hardness Machine Brinell Hardness Test Equipment Knoop Hardness Test
HBRV-187.5DX Senior Digital Brinell, Rockwell, Vickers Universal hardness testers series ( with Touch Screen)
Brief Introduction
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, tiredness, wriggling and wearing out can be tested out approximately through its hardness testing .
Digital multi-functional hardness tester with Brinell, Rockwell, Vickers three testing methods, multi-functional hardness tester of seven grade test force ,it can meet the needs of a variety of hardness tests. Test force loading, dwell, unload adopted automatic switching mechanism, test force transformation obtained by the rotation of hand wheel, indentation measured by precision encoder and sensor and calculated the hardness value by the internal system program. So it is easy to operate, fast and intuitive interface, basically, no human operation error, with its high sensitivity, stability, it is suitable for workshops and laboratories.
The main function as follows:
Main features:
2. Electronic and electric loading, high precision sensor, with a unique closed-loop control system
3. Eyepiece structure with digital encoder, measuring D1, D2 value, LCD directly display hardness value and D1, D2 value
4. Directly select the hardness scale, the force value automatically changes in the test parameters
8. The hardness values of brinell, rockwell and vickers can be converted
