The Rex H-1000-A Type A Mini Dial Durometer RX-1000-A for Soft Rubber, Plastics and Elastomers is compact and easy to use. Its small dial face and included leather clip-on carrying case make it easy for an inspector to carry the gauge- for work around the shop, or out in the field. The RX-1000 durometer holds the maximum reading until reset by pressing the button at the top of the gauge. The max-hold feature and small dial size make the Rex RX-1000 a good choice for hard to reach places, or for out of sight testing.
