Clark Hardness Testers CPT

Portable, Reliable & Accurate

The Clark CPT Series portable testers offer a reliable solution for “Rockwell” testing in areas where clearance is limited, allowing for testing both inside and outside surfaces at any angle. Quick change indenter, easy to read dial indicators, and finger tip loading make the CPT a handy and efficient tool for testing large or difficult to access parts.

Special Features:

  • Accurate "Rockwell" scales, A,B,C,D,E,F,G,H & K readings
  • Durable design withstands harsh environments
  • Lightweight
  • Conforms to tolerances per ASTM & ISO 17025 Standards
  • Certified and ready to use
