TH140 Leeb Hardness Tester is a new type of portable hardness tester with high precision, small size, easy to use, convenience to carry, and has a feature of wide measuring range. It is established on principle of Leeb hardness, and the tester measured Leeb hardness (HL ) values, then through programs automatically converted to Brinell and Rockwell, Vickers, Shore hardness, etc. It can also configure a variety of testing accessories, to meet a variety of test conditions and environment
·can test six hardness systems (HV, HRC, HRB, HB, HV, HS);
·A machine can be also equipped heterotype impact device with a variety of special-shaped (D, DC, D +15, C, DL, G)-type;
·Automatic identifies Impact device type (D, DC, D +15, C, DL, G);
·can be set upper and lower hardness values automatically sound alarm.
·screen with backlight, adjustable contrast;
·can store 48 to 350 group test data;
·printer and the host are detachable, easier to carry;
·increases material (stainless steel) for test and expands the scope of the test;
·Automatically detects the battery voltage, when the operating voltage below the rated value, it can automatic alarm;
·Displays battery value;
·can print test results;
·Chinese menu for easy operation
