Durometers are used in a wide range of settings to provide a quick check of the hardness of certain materials. Typically used for determining the hardness of plastics or rubber, these devices are designed with a retractable plunger style indentor which has a shape and resistance based on material to be tested. The indentor travel correlates to a readout with a 0 to 100 scale, indicating material hardness with higher values indicating harder material.

With such a variety of materials, durometer models range from A, B, C, D, E, DO, O, OO, OOO, OOO-S, M, and R on the Shore hardness scale, with testing standards ASTM D2240 types A and D as the most common reference. However an ASTM D2240-00 covers a total of all 12 scales.

J.A. King offers ISO 17025 accredited durometer calibration with NIST traceable master testing standards such as gage blocks, durometer test blocks, vision systems, and durometer calibrators.

Our durometer calibration procedures require our experienced technicians to measure the geometry of the durometer indentor, verify its travel, and use a minimum of three durometer test blocks to take average readings across the entire scale. This data is then stored for easy 24/7 access within GageSuite, our cloud based calibration management system.
