 3. MAIN FEATURE

• This hardness tester can test many kinds of metal materials with high precision.Accord with standard JB/T 9378-2001 in [Technical conditions of Leeb hardness tester].
• DISPLAY shows 2 scales : the hardness scale of Leeb and the other corresponding scale.
• Dedicated circuit design, probe hot plug support. 
• Seven impact devices are available for special application; Support plug and play. it can automatically identify impact device and can set by manual as well. No need calibration when probe changes.
• Ten commonly used material of hardness scale(HL, HB, HRB, HRC, HRA, HV, HS) parallel conversion.
• Added 3 materials for the roller hardness tester(optional): cast steel roller, forged steel roller, cast iron roller: cast steel roller, forged steel roller, cast iron roller. it can take quick measurement for roller.
• Five (1-5)user's materials can be defined for hardness testing of special materials. Theoretically, this tester tests all metal materials.  
• Built in lithium ion battery; up to 50 hours continuous work; with auto sleep, auto power off, power-saving features.
• Adopt 320X240 true color large TFT display.
• Windows menu. Support 6 language freely switch. User friendly features, easy to operate.
• the Brightness of LCD allows adjustable, it improves visibility in dark environments.
• Material of 'steel' is added; HB values can be read out directly when D/DC impact device is used to measure "steel" work piece.
• USB port. Convenient communication with PC to exchange data and set parameter.
• Large memory up to 600 group hardness data( impact times:32~1), it include: the last testing value, average value, testing date, impact direction impact times, material, hardness scale, etc
• it can automatically alarm when values are out of pre-set range, which is convenient for the requirements of batch measurements.
• Metal case, anti-electromagnetic interference, shock resistant.
• There are remaining charge indicator, charging hint.
• Features calibration function.
• Software of PC can be installed according to the requirements of user, the function will be more powerful to satisfy the more strict demands of quality control and management.
• Add user defined material.
