Mitech MH660 Portable Leeb Hardness Tester
MH660 portable Leeb hardness tester is Mitech latest upgrade model, it focuses on user experience and innovative features. 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.
It is 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.
