Our new DD-300 Durometer range takes rubber / plastic hardness testing to the next level.
This DD-300 hardness tester has been designed to have almost no internal friction and therefore meets the highest quality standards.
The entire internal movement is guided by bearings and makes this one of the best digital durometers available today.
The DD-300 Durometer is available in Shore A, C, D, O, OO, AO, DO and Asker C.
