Name: CISAM-ERNST Computest Lite Portable Hardness Tester
Brand: CISAM-ERNST

Direct Rockwell readings without a tablet

Computest Lite is a simplified portable Rockwell hardness tester for users who need direct, fast and simple testing without data management. It works with a 5 kgf / 49 N test load and tests ferrous and non-ferrous metals without changing the diamond indenter.

It can be used in every position and is not affected by sample mass, deflection or elasticity. Results appear directly on the onboard display. Compared with e-computest, it needs no tablet, software, language setup or wireless data sharing, and it suits on-site testing of large workpieces, thin parts and general metal quality control.
