LS252C Leeb Hardness Tester

Ideal for testing the hardness of surface hardening layers and parts with small masses or thin thicknesses

Adopts Impact device C
Dual coil technology for good measurement accuracy and repeatability
Probe with orientation sensor for full angle measurement

The LS252C is an all-in-one hardness tester with a compact size for hardness measurements on various metal materials. Featuring a C-shaped impact device with low impact force, it is suitable for testing the hardness of surface hardening layers and parts with small masses or thin thicknesses. The instrument uses advanced dual coil technology for good repeatability and high measurement accuracy. The probe has a built-in orientation sensor, which automatically compensates for measurement errors in different impact directions. The system has five hardness scales, which can be interchanged between Richter (HL), Vickers (HV), Brinell (HB), Shore (HS) and Rockwell (HRC) to avoid tedious manual calculations.

Application

The instrument uses a impact device C with many metal materials choices for wide applications.
