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.

We ship via ground service prepaid at no charge to all U.S. commercial addresses, and correspondingly discount all residential and air shipments. Minimum order $40.00.

*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.
