Rex Model 2000 Standard Dial Durometer
The Model 2000 Max-Hand Durometer is designed to test 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. 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.
What makes the Model 2000 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, and makes the Max-Hand 2000 the most affordable durometer for critical testing of specimens with creep.
The Model 2000 is available in Types A, D, B, C, DO, E, and O. They all conform to ASTM D2240, and 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 he durometer reading instantaneously. 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.
