Introduction The new Check-Line AD-100 analog durometer is the ideal choice for a wide range of Shore hardness measuring applications. The AD-100 displays hardness readings on an easy-to-read analog scale calibrated in 0 to 100 Shore units. Seven scales are available: A, B, C, D, DO, O, OO.
Testing Procedure 1. Place the instrument on the material to be tested. The durometer must be level and perpendicular to the specimen. Any angle other than perpendicular (90°) may cause errors. NOTE: If the gauge is equipped with the Memory Pointer option make sure the pointer is returned to zero before starting.
memory Pointer (optional) The Memory Pointer moves mEmOry POINT- with the measurement pointer when a measurement is taken. However, when pressure on the KNurlEd KNOb specimen is released, and the measurement pointer returns to zero, the Memory Pointer remains in position, marking the last measurement.
* NOTE: per ASTM D 2240-05, Sect 9.3: It is accepted that durometer readings be- low 20 or above 90 are not considered reliable. It is suggested that readings in these ranges be omitted.
