Product details

The quality of the Leeb hardness tester and the displacement of the sensor are one of the standards for distinguishing instrument performance. The advantage is that it can be equipped with seven types of impact devices, which are automatically recognized by the host and do not require recalibration when replacing. Different impact devices measure different ranges and measure different shapes of workpieces.
