PTC® Durometers / Shore® Hardness
Shore Hardness Scale
PTC® Instruments manufactures durometers to meet or exceed ASTM D2240 and offers A2LA calibration services accredited to ISO/IEC 17025 ANSI/NCSL, Z540-1.
A durometer is an instrument for testing the hardness of various plastics & rubber. ASTM D2240 Standard Test Method for Rubber Property, Durometer Hardness. This test method covers twelve types of rubber hardness measurement devices known as durometers. (See Shore Hardness Scale below) Durometer Tech Sheet

PTC® Instruments manufactures durometers to meet or exceed ASTM D2240 and offers A2LA calibration services accredited to ISO/IEC 17025 ANSI/NCSL, Z540-1.
These durometers can be used either with a test stand, hand-held or with the constant load weight. Please refer to the stand selection guide for appropriate instruments. The PTC® Durometers come complete with carrying case and test block.
Our sales department (310-478-1134) will help you determine the correct durometer for your hardness test. We offer material testing to determine the correct durometer type and style for your application at no charge.
Durometer Calibration & Repair
If you need to return an instrument for calibration and/or repair, please fill out our Return Authorization Form. One of our specialists will email you an RMA number and instructions to send in your unit. Turn around time is usually 3 to 5 days from the date it arrives at PTC Metrology™
All Calibration Standards are traceable to the National Institute of Standards and Technology (NIST). Durometer calibration services and reports are provided by PTC Metrology™ and will meet your ISO, ANSI, MIL, DoD, EuroNorm and other international standards including DIN 53505, ISO 868 and ISO 7619.
PTC® manufactures Durometer Test Stands. The test stands are designed to provide the ASTM recommended forces for use with PTC®'s Durometers and are also fully compatible with durometers of other manufacturers.
NOTE:
Any e2000 Millennium Style Durometer can be made as an "R" designation. The "R" designation specifies a presser foot diameter of 18 ± 0.5mm (0.71 ± 0.02in) in diameter, while the spring forces and indenter configurations remain the same. Please specify the "R" Type when ordering. US Patent D436,874
