Rex Durometer Test Block Kit for Type OO

Since type OO and OOO durometers test soft rubber, foams, gels and other very soft non-metallics, it is possible for the user to imbed the foot of the gauge into the test specimen and obtain false readings. To obtain accurate readings using a durometer, one must develop a proper “feel” for the gauge. Rex Gauge Co.’s Test Block Kit for OO and OOO durometers gives the user the ability to develop the proper “feel”. While not to be used for calibration purposes, the kit also enables the user to perform a quick check for the proper operation of the durometer.

The kit consists of five color coded test blocks each measuring 1/4″ x 2″ x 2″. The blocks are calibrated at Rex Gauge Co. and correspond to durometer values of 20 pts. to 60 pts. in increments of 10 pts. The Kit is furnished with 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 conformance is also available for users who need documentation of tracibility to NIST.
