This kit will prove to be invaluable in helping to maintain durometer read-out accuracy for science, manufacturing, research and development. The test kit consists of 7 test blocks. The individual test blocks are provided with serial numbers to guarantee incontestable identification.
The hardness values are ranging from 30 durometer to 90
durometer type A. As a reference check, it will indicate if a durometer is operating within tolerances. A durometer should never be calibrated with test blocks. For durometer calibration we recommend our Durometer Calibrator Model RC-1. The material from which the test blocks are made is fairly stable, however, it is strongly recommended that the calibration of the test blocks be verified annually.
7 test blocks size approx. 54 mm x 54 mm x 8 mm
