Durometer system. (Instruments).

The OS-2H durometer operating stand is said to provide a convenient and accurate way to perform repeated hardness testing. The OS-2H provides the correct testing pressure as noted in ASTM D-2240, as well as an adjustable dampening feature. The dampener lowers the gauge at the same rate for each test, resulting in superior repeatability, according to the company. The OS-2H can be used for durometer types A, B and O (custom brackets are also available for use with other gauge makes). The RDC-1 durometer calibrator is said to be easy to use. Unlike a conventional scale, it does not require the fabrication of a fixture to hold the gauge, and the user does not have to perform any calculations to determine if the gauge is in calibration. With the RDC-1, the user simply secures the gauge in the clamp and slides the weight to the appropriate point on the scale, according to the company. If the gauge reads within [+ or -] 1 of the point indicated on the scale, it is in calibration. The calibrator is delivered fully calibrated, with documentation traceable to NIST. The RDC-1 allows users to check calibration in the A, B, C, D, DO and O durometer types, and is furnished with an adapter which allows the user to check the calibration of competitive gauges.
