Rex Model: Operating Stand OS-1 


The Rex OS-1 Operating Stand is the ideal tool for repetitive or lab-type testing for users who must test either very large specimens, or test in a number of different durometer scales. The Rex OS-1 Operating Stand, used in conjunction with a Rex durometer eliminates the operator error sometimes associated with shop floor durometer testing. The stand features a floating pin and includes the proper load weights required for testing in durometer scales (A, B, C, D, DO, O, OO, and OOO), as noted in ASTM D2240. The OS-1 can accommodate specimens varying in size from a 6 millimeter (quarter inch): to 25.4cms (10 inches) thick. (custom stands for testing larger specimens available)
