Test the hardness of thin and irregularly shaped plastic, rubber, and laminate parts, such as O-rings. These testers can be used on products where the surface area is too small for accurate durometer readings with a standard Shore A tester, such as the rounded surface of O-rings. They include O-ring fixtures that hold five standard-sized O-rings in place during testing. These testers are also capable of measuring materials as thin as 0.05″, about the thickness of a credit card. On the display, they’ll show the highest reading until they’re reset. They include a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Use the included test blocks to practice taking accurate measurements at the right pressure against your workpiece. Send your measurement data directly to your PC using the USB port.
