The Check-Line OS-4 Test Stand is designed for use with our type OO & OOO durometers. The stand, used in conjunction with our Durometers increases repeatability while eliminating operator error.
The stand features a load weight for the proper testing pressure as noted in ASTM D2240, and a quick-lock column for easy adjustment.
The OS-4H features an a dampener that lowers the durometer at the same rate for each test, resulting in superior repeatability for all durometer tests
