Rex Model 3000 Standard Dial Durometer

The Model 3000 Max-Hand Durometer is is Rex Gauge Co.'s latest innovation for the testing of specimens that exhibit creep (the increasing penetration of the anvil into the specimen over time) – it utilizes a max-hand and an active hand for observing the creep characteristics of a specimen. The Model 3000 features a larger grip with an expanded 18 mm (0.70") presser foot diameter for more secure and repeatable positioning. Its large 2.25″ (5.7 cm) dial face with full 360° dial sweep allows discernment to within 1/2 point, the maximum accuracy available in a dial model gauge. Note: Increasing foot diameter can affect durometer readings - using the appropriate Test Block Kit can verify durometer operation.

What makes the Model 3000 unique is the magnetic-drag maximum reset mechanism. The user simply rotates the reset knob on the front of the gauge to clear the previous reading. The simplicity of the reset mechanism ensures a lifetime of use.

The Model 3000 is available in Types A and D. They both conform to ASTM D2240, as well as DIN 53505, ISO 868, and ISO 7619. They usually ship without delay directly from the manufacturer.

Instructions for use:

Rotate the reset knob until both hands meet. This places the max hand in position for testing. Hold the durometer in a vertical position and press the foot of the gauge firmly against the specimen, but not so firmly as to imbed the foot into the surface of the material – a force of 1 kg (2.2 lbs.) is ideal. The max hand will indicate the instantaneous durometer reading. The regular dial hand may recede from this maximum after a few seconds. This indicates creep or cold-flow of the specimen.

Note the maximum reading from the max hand and also note the creep reading after a given time delay while maintaining firm contact of the foot against the specimen. An example of a properly noted durometer reading: “Durometer A 61, creep 7 at 15 seconds, 73°F” (the notation “creep 7” would reflect a test where the reading dropped from 61 to 54 over the time span cited). Repeat these steps for each use. At rest position the durometer should read zero.
