MH660 portable Leeb hardness tester using 320 × 240 color LCD display, can also present a clear measurement results in dim light and strong sunlight environment , greatly enhance the visual experience; sealed metal case compact design, smaller, better quality, designed to withstand harsh field environment of the oil, dust ,more original point calibration function is used to do  multi-point calibration for convert curve to reduce errors;

during measurement instrument can automatically identify the measuring direction, automatically alarm when out of range,  to meet the inspection requirements with high precision and multi-angle material collected, support free conversion between hardness type; low-power design powered by two AA batteries,  support multiple languages, blue-tooth printer. 

Widely used in metal processing and manufacturing, special equipment or permanent component failure analysis in service, inspection and other fields. Particularly suitable for large non-removable part of the site hardness testing. It is to improve the pass rate of production and cost savings necessary professional precision instrument.
