The Digital Complete O-Ring Hardness Kit is the most convenient and accurate way to perform repeatable hardness (durometer) testing on thin materials – as thin as .030”*.
The OTK-DG is comprised of the following items:
Model RX-DD-M - Type M Digital Durometer with Certification
RX-ORF - O-Ring Fixture Kit (1/16, 3/32, 1/8, 3/16, 1/4)
Model RX-OS-3 - Air Dampened Operating Stand
RX-TBK-A - Test Block Kit with Certification
*Although the ASTM specifies that Type M Durometers can be used to measure O-Ring diameters as thin as 0.050" (1.25 mm), this system works well to 0.030" (0.75 mm)
