Ergo Style Durometers from PTC®

The Ergo Style Durometers from PTC Instruments are built to meet or exceed current ASTM D2240 and ISO 868 specifications. The 400 Series Durometers measures the indentation hardness of rubber, elastomers, and other rubber-like substances, such as neoprene, silicone, vinyl, nitrile, and butyl, acrylic, delrin, kevlar, pvc, nylon and lexan. It can also be used for soft plastics, felt, leather, and similar materials. The Ergo Style Durometers are available in Type A, B, C, D, DO, E, O and OO.

These durometers can be used either with a test stand, hand-held or with the constant load weight. Please refer to the stand section guide for appropriate instruments. The PTC® Ergo Style Durometers come complete with 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. For complete calibration services please refer to PTC Metrology an A2LA Accredited Laboratory.
