Product Description

Rex Durometer Operating Stand: Models OS—3

Rex Gauge Co. introduces the OS-3 compact operating stand for the operation of durometers in the M scale (as per ASTM D2240). The stand, used in conjunction with a Rex Durometer, eliminates operator error sometimes associated with shop floor durometer testing. The stand features a load weight for the proper testing pressure as noted in ASTM D2240, a quick-lock column for easy adjustment plus a dampening feature. The dampener lowers the durometer at the same rate for each test, resulting in superior repeatability for all durometer tests. It can be used with either the provided specimen holder or the optional Rex Model ORF-1 O-Ring Fixturing Set (sold separately).
