How do you use a Rex durometer?
Operating Instructions Hold the durometer in a near-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). The indicator hand will come to a stop, indicating the durometer (hardness value) of the specimen.
What is a durometer gauge?
A durometer gauge or durometer tester is needed to perform a durometer hardness test procedure. Each durometer or hardness tester measures the depth of an indentation in the material caused by a defined force of a given geometric presser foot. The depth of the indentation reflects the hardness of the material.
What is durometer 70A?
A durometer scale is a type of measurement of rubber material hardness. A rubber durometer of Shore 70A is the most commonly chosen material hardness for all applications.
What is durometer 40A?
Shore 40A = Pencil Eraser.
How does the durometer scale work?
The Shore durometer is a device for measuring the hardness of a material, typically of polymers, elastomers, and rubbers. Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials.
How do you convert durometer to Young’s modulus?
For a durometer given in Shore-A, multiply this value by 0.0235. Then subtract 0.6403 from this result. The next step is to find the inverse base-e logarithm of this new result. The answer is an approximation for Young’s Modulus in megapascals (MPa).

How do I know if my durometer is working properly?
To make a simple operation check, take a reading on smooth glass or steel (WARNING: THIS IS NOT RECOMMENDED FOR TYPE D DUROMETERS – THE GAUGE MAY BE SEVERELY DAMAGED). The gauge should read no more than 100 and no less than 99. In a Rex Durometer, the unique built-in linearity assures the gauge is in proper operation throughout the entire scale.
Can a Rex durometer give a false reading?
This will give a false reading due to the “anvil effect”. The Rex Type M durometer can be used when checking materials thinner than 1/4″ (as thin as .050″). When testing flat specimens too thin to give accurate readings, the specimens may be stacked to provide the required thickness.
