Test Blocks for Durometer A:
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.
Test Blocks for Durometer D:
Three test blocks with hardness values of approx. 60, 75 and 85 type D are available for testing durometer type D. An annual calibration of the test block is strongly recommended.
Test Blocks for Durometer OO:
Three test blocks with hardness values of approx. 35, 60 and 80 type OO are available for testing durometer type OO. An annual calibration of the test block is strongly recommended.
