Custom Durometers from PTC Instruments
Accredited by A2LA to ISO/IEC17025 and ANSI/NCSL Z-5401

PTC® Instruments has been manufacturing a full line of quality durometers and durometer accessories since 1946. Our durometers are made to meet or exceed current ASTM D2240, ASTM F1957, JIS, and DIN standards. PTC's engineering and applications department has manufactured numerous custom configurations for unique or unusual materials. Listed below are a few custom durometers that are currently being used today.

PTC® Instruments will help you determine the correct durometer for any application at no charge. For custom applications PTC® will evaluate your material and recommend a durometer type or recommend a custom configuration based on your specific material and hardness range. Selecting the correct durometer type has become increasingly more difficult due to the large number of instruments and standards available today.
