Constant Pressure Weighting - For Durometers

This is a oil pressure type measuring instrument by load of constant speed / pressure ,which has dissolved personal difference by load pressure to measure rubber hardness. Each durometer of type A, E,B,O SRIS with fixing around 1kg weight and type D, DO, C with fixing 4kg weight can measure by static loading around 5kg.
These load figures are indicated in ISO, JIS, ASTM.
