Clark Analog Portable Rockwell Hardness Tester

Clark Analog Portable Rockwell Hardness Tester

The Clark Portable “Rockwell” tester models CPT and the larger CPT-XL are heavy duty testers with quick change Indenters, easy-to-read dial indicators and precise fingertip loading.

These testers are well suited to test pieces that are too large to conveniently test on a Bench tester, as well as inaccessible parts. The affordable price also make them a cost effective substitute for a Bench “Rockwell” tester for smaller shops and for those people who only have an occasional need.

The CPT and CPT-XL use standard Rockwell loads of 150, 100 and 60 kg. They are supplied with a 1/16″ steel ball indenter for HRB measurements. A diamond cone indenter is an available accessory for HRC and HRA scale tests. A 1/8″ ball indenter for softer and thinner materials.
