Digital durometer tests rubber hardness.

The S1 durometer is said to be ideally suited for hardness testing of rubber and plastic. One feature of the S1 durometer is its ability to set a test dwell time from one to 25 seconds. An audible system tells the operator when the time is complete, ensuring that the test forces are applied for the same amount of time during each test, significantly reducing operator errors due to inconsistent dwell times, according to the company. A tolerance audible alarm can also be set to easily identify parts that are out of the acceptable hardness range.

The S1 durometer can be used in place of many durometers because of its modular design, which is comprised of a digital display head and detachable presser foot probe that facilitates changing test scales. A common display unit can be used to test in any of the standard Shore scales by simply changing presser foot probes. To guarantee accurate and precise test measurements, results are displayed on a high contrast LCD either as a single test or the average of several tests, omitting the need for operator calculations, according to the manufacturer. The S1 durometer stores 256 test results and can automatically send all results to a PC via an RS 232 connection.

This company is said to offer a wide range of materials testing instruments designed to determine the hardness of rubber, elastomeric, cellular and rigid plastic materials. The products are said to be used in various industries, including automotive, printing, sporting goods, rubber and plastics. Specifically, the durometers and durometer systems are used extensively to test the hardness of footwear and athletic shoes, automobile tires, injection molded rubber parts, printer rollers, golf balls and o-rings, according to the company.
