The Clark CPT tester is a lightweight tester for portable testing of Rockwell hardness, with a wide range of sample sizes accommodated.  This unit includes a Rockwell B 1/16” ball indenter, and other indenters are readily available.  Easy to use, and can perform all Rockwell scales at 60kg, 100kg, and 150kg force.  Very good condition, in original case with HRB test block and operation manual.  [INV224]
