At Checkline.com, we strive to provide durometer hardness testers that will work, no matter what your testing environment is or what material you need to measure. We carry durometers that meet or exceed ASTM D-2240, DIN, ISO, and JIS standards. We offer Asker durometers as well as Shore A durometers, Shore D, and the rest of the Shore scale. Our inventory includes analog and digital durometer testers, in handheld designs or for use in test stands. We offer multi-scale Shore durometers, pocket and pencil styles, and slim probes for working in tight or hard to reach areas. Choose a durometer scale specifically for measuring skateboard wheels, rubber tires, gym shoe soles, or textiles.

We also offer all the durometer tester accessories you might need. Keep your Shore durometer working accurately with our durometer calibrator or develop a “feel” for your durometer hardness gauge with our test block kits. Choose our PC lab software to log measurements and chart data or the data collection system with tablet and Android App for use some of our digital durometer testers. We carry test stands for greater testing accuracy than handheld measurements, or testing kits for O-Rings and very thin materials.
