Type M Test Block Kit
Since type A durometers test rubber and other softer non-metallics, it is possible for the user to imbed the foot of the durometer into the test specimen and obtain false readings. To obtain accurate readings using a durometer, one must develop the proper "feel" for the gauge.
This test block kit is specifically engineered for use with Model 1600M or DD-4M durometers, which can test specimens with a thickness of only .050″ (1.25 mm) to .250″ (6 mm). It gives the user the ability to develop the proper “feel”, and, while it is not to be used for calibration purposes, it enables the user to perform a quick check for proper durometer operation. The kit consists of seven color-coded test blocks each of which measures ¼″ x 2″ x 2″ (6 mm x 51 mm x 51 mm). The blocks are calibrated at Rex Gauge Co. and correspond to durometer values of 30 pts. to 90 pts. in increments of 10 pts.
The kit comes to you in a sturdy magnetic-latching carrying case with the true readings for each block on the inside cover of the case. At an additional cost, a Certificate of Calibration is also available for users who need documentation of traceability to NIST.
