Hardness tester TH140 Leeb hardness tester

Leeb hardness tester is a new type of portable hardness testing instrument, mainly is suitable for the test of metalmaterial hardness, high test precision, small volume, easy operation, convenient carrying, the characteristics of wide measuring range, which is based on the principle of Leeb hardness as measured on the Richter scale (HL), the hardness values through the program automaticallyconverted into Brinell, Rockwell hardness value,Vivtorinox, Xiao exhibition, can also configure various test accessories, to meet in different test conditions andenvironment, rapid hardness test is mainly suitable formetal materials, especially suitable for the field of hardness test for large parts and non removablecomponents.

Function characteristics:

● can test six kinds of hardness of system (HV, HRC,HRB, HB, HV, HS);

The machine can be also equipped with a variety of special-shaped impact device (D, DC, D+15, C, DL, G)type;

Automatic identification device for impact type (D, DC,D+15, C, DL, G);

● can set the hardness value deviation automatic voicealarm;

● screen with backlight, adjustable contrast;

● can be stored for 48 to 350 groups of test data;

The printer and the host can be separated, more easy to carry;

● increased the test material (stainless steel) and the expansion of the scope of testing;

Automatic detection of battery voltage, when the voltage is lower than the rated value, the automatic alarm;

● the battery consumption;

● can print test results;

● full Chinese menu, convenient operation
