Mattel MH320 portable Leeb hardness tester based on the hardness measurement, can be measured easily and quickly on a variety of materials, hardness measurement values are displayed at the same time, you can freely switch between different hardness standard, allows for preset tolerance limit, out of range alarm. This product adopts international popular thermal printer and instrument integration as a whole, and quiet, fast print speeds, you can print test reports. I c relying on stable low power consumption of integrated circuits, Chinese display, menu-driven operation is simple and convenient, seven special impact device without calibration, automatic recognition. USB interface transfer, mass storage, attached to the PC machine and human data-processing software and the USB plug-and-play cable. 150 hours of standby time, built-in rechargeable Ni-MH rechargeable batteries and control circuits, and easy to carry. Ideal for job site and field work.

·According to Leeb hardness measuring principle, the detection of multiple materials.

·A host can be equipped with 7 different impact devices, automatically identifies impact devices types, replacement without recalibration.

·Support ' forged steel (Steel) ' material when using a D/DC impact device test ' forged ' sample can be directly read HB values without manual look-up table. On the hardness value can be pre-set limit, out of range alarm, convenient batch testing needs.

·128x64 the big screen graphic dot matrix liquid crystal display, information-rich and intuitive.

·Chinese display, menu-driven operation, the operation is simple and convenient.

·EL backlight display, convenient for use in dimly lit environments.

·You can store up to 500 groups (impact and number of 32~ 1) hardness measurement of data, each set of data including single measurement values, the average measurement date, impact direction, frequency, material, hardness and other information.

·Thermal printer and instrument integration as one, quiet, fast print speeds, you can print test reports. Software calibration.

·Built-in rechargeable Ni-MH rechargeable batteries and control circuits; Not less than 150 hours of continuous operation; Has auto sleep, energy-saving features such as automatic shutdown.

·The remaining battery indicator icon on the LCD, real-time display battery life; Indicates the charging process, the operator can keep informed of doc.

·USB interface, you can easily and quickly Exchange data with the PC machine. Can be equipped with the software, transferring measurement results, measured value storage management, statistical analysis of measured values, print a measurement report, rich features such as bulk set the instruments parameters to meet the higher demands on quality assurance and management.
