Closed-Circuit System Digital Electronic Brinell Hardness Tester MHB-3000

Main characteristic features:
MHB-3000 Digital Electronic Brinell Hardness Tester is a unified product combining optical, mechanic and electronic techniques, which is adopted the precise mechanical structure and computer control closed-circuit system. Without the weights, the instrument loads and unloads the testing force with the motor. By means of the 0.5‰ accuracy compression sensor to feedback the information and the CPU to control, the instrument compensates automatically the testing force lost during the testing.

Equipped with a digital micro eyepiece on the instrument, the length of indentation can be measured by this eyepiece directly. All testing data such as the testing method, the testing force value, the length of testing indentation, the hardness value and the dwell time of testing force can be showed on the LCD screen, without inputting the value of diagonal length for the indentation and free from looking up the hardness value form the hardness table as well, therefore the reading data are more accuracy and operation of this instrument is more easy.
