| 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.
