high precision.Accord with standard JB/T 9378-2001 in [Technical
conditions of Leeb hardness tester].
- Dedicated circuit design, probe hot plug support.
- Seven impact devices are available for special application; Support plug
and play. it can automatically identif 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.

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.
