Rex 1600M Micro Dial Durometer

Rex's Model 1600 durometers are best-sellers for good reason – their large 2.25″ (5.7 cm) dial faces with full 360° dial sweep allow discernment to within 1/2 point, the maximum accuracy available in a dial model gauge – all at a minimal cost.

The Model 1600M uses a sharp cone point indentor, with a spring force of only 78 grams to test specimens as thin as .050″ (1.25 mm). It is available in Type A only, and gives readings to approximately +/- 2 points compared to those determined by a standard Type A durometer.

The Model 1600M conforms to ASTM D2240 only if used with a dampened operating stand with a controlled rate of descent (Model OS-3). The Model 1600M is generally available from stock.

*If used with a controlled descent operating stand.

Instructions for use:

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 dial hand gives the reading in durometer points. Creep or cold-flow of the specimen, if present, will be evident by receding action of the dial hand.

Note the initial reading, and again, the 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 90-95.
