PTC Ergo-Style Durometer

PTC®  Instruments's 400-Series Ergo-Style Durometer measures the hardness of a range of materials from foam and sponge rubbers to hard rubbers and plastics, including epoxies. Featuring a smaller foot than their Classic Style, the Ergo-Style Durometer enables hardness measurement of materials with smaller accessible surface areas. All PTC Durometers meet or exceed American Society for Testing and Materials (ASTM) D2240* Specifications.

Ergo-Style Durometers feature a low-glare, serialized dial with bold, easy-to-read numbers, and is supplied standard with a Max Hold hand which maintains the peak reading until reset. The durometer body tapers to a 1 inch square base to allow better access to confined areas. A removable top knob (8-32 threads) permits both easy hand-held use or attachment to stands; the PTC Ergo-Style Durometer can be used with a test-stand, hand-held, or with a constant load weight. Accurate hardness readings can be obtained in any position.

Each PTC Durometer is individually calibrated, and ships complete with customer-selected scale, carrying case, test block, and a magnetic Max Hand that holds the peak reading until reset. A test report is included for A & D models which notes the value at 20, 40, 60 & 80.

  • Meets or Exceeds Current ASTM D2240 Specifications for Durometers
  • Accuracy of ±1 Point
  • Base Tapers to 1" x 1"
  • NIST Certification Available
