Portable Leeb Rebound Hardness Tester Support D DC DL D+15 C G E Probe


1. Material of 'steel' is added; HB values can be read out directly when D / DC impact device is used to measure ‘steel’ work piece.

2. Adopted 320x240 true color large TFT display;

3. Display shows double scales: HL value and Conversion value (HRA / HRB / HRC / HB / HV / HS);

4. Ten commonly used material of hardness scale (HL, HB, HRB, HRC, HRA, HV, HS) parallel conversion.

5. Brightness of LCD allows adjustable, it improves visibility in dark environments;

6. Dedicated circuit design, support probe hot plug. 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;
