Instrument Features

1. This unit can store 255 sets of measurement data, including single measurement value/average value/measurement date/impact direction/number of impacts/material/hardness system, and other information.

2. Can connect to a portable Bluetooth thermal printer via Bluetooth.

3. Data storage: maximum 255 sets (each set with 01~12 impacts).

4. Chinese and English can be switched freely, facilitating on-site communication with foreign clients.

5. Equipped with "Forged Steel" material; when testing "Forged Steel" samples with D/DC type impact devices, HB values can be read directly, eliminating the need for manual table lookup.

6. Has calibration function with evaluation software.

7. Uses digital impact devices, compatible with all 7 types of probes; automatic probe type recognition, no recalibration required when changing probes.

8. Allows preset upper/lower hardness limits; automatic alarm when out of range, meeting user testing needs.

9. Design based on standard: "Technical Specifications for Leeb Hardness Testers" JB/T 9378-2001.
