LR140 portable hardness tester


Model LR140 portable hardness tester can directly measure different types of hardness value including (HRC, HRB, HRA), Leeb (HL), Brinell (HB), Vickers (HV),and Shaw (HS). In accord with international standards it’s also can meet the “Leeb hardness tester technical conditions ZBN7l 010-90” and the “metal in the hardness test method GB / T 17394-1998” Leeb hardness standard JB/ T9378-2001 standards which are issued by the Ministry of Machinery Industry and National Quality and Technical Supervision.

One LR140 main device can be equipped with seven different impact devices which identify the impact of device type automatically and replaced without recalibration. With low-power design and high-performance Li batteries which can achieve ultra-long standby time work it has more compact and flexible design increases user flexibility.
