Portable Hardness Tester
GH100
Date：2023-02-21
Model GH100 series portable hardness tester
[Introduction]
GH100 Series includes Model GH100D, GH100DC, GH100C, GH100DL and GH100D+15, meets various measuring conditions, for detailed information, please see appendix files.
Model GH100 series 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.
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.
[Features]
