MHV-5/10/30/50 Large Screen Digital Vickers Hardness Tester
Vickers hardness tester manufacturer in China
Features and Applications:
*High-tech and new product combining the optics, mechanic and electrics features.
*Adopts load cell control system, improves the precision of the test force and the repeatability and stability of the indicating value.
*Adopts LCD display screen,visual and clear, easy to operate.
*With digital measuring eyepiece, no need for checking the table or inputting the diagonal of the indentation, it can directly show the test force, indentation length, dwell time, test numbers, conversion scale, date and time.
*Press the eyepiece button after measuring the indentation length,and it can automatically get the hardness value and shows on the screen.
*Test results can be saved in real time with automatic calculation of maximum, minimum and average value, the data can be arbitrary deleted and printed out, and with RS232 interface for connecting to the computer.
*It can be equipped with LCD video measuring device and CCD image automatic measuring system.
* Precision conforms to GB/T 4340.2, ISO 6507-2 and ASTM E92
Suitable for ferrous metal, non-ferrous metals, IC thin sections, coatings, ply-metals; glass, ceramics, agate, precious stones, thin plastic sections etc.; hardness testing such as that on the depth and the trapezium of the carbonized layers and quench hardened layers.
