low price Digital Portable hardness tester

MH310 Portable Hardness Tester based Leeb hardness measuring principle, can quickly and easily measure a variety of metal materials, hardness measurements instantly displayed simultaneously, you can freely switch between different hardness standard, can be pre-set tolerance limits, out of range automatic alarm. The product uses the international popular thermal printer integrated with the instrument as a whole, and to work with quiet, print speed, print test report can live. Relying on stable, low-power IC integrated circuits, high-contrast LCD segment code, simple and convenient. Seven kinds of special-shaped impact device without calibration, automatic identification. USB interface, mass storage, along with user-friendly PC-USB plug and play data processing software and data cable. 150 hours of standby time, the built-in NiMH rechargeable batteries and charge control circuit for easy carrying. Particularly suitable for field work and field operations.
