New hardness tester offers automated testing and accurate results

Hardness testing is one of the most critical tests used to determine the characteristics of a material and its suitability for a given application. It is typically undertaken to assess resistance to plastic deformation, a value of tremendous importance when determining part quality in a wide range of industries and applications.

A common test used to determine material hardness — the mean pressure a material will support — is the Rockwell hardness test, a measurement based on the net increase in depth of impression as a load is applied. In the Rockwell method, the depth of penetration of an indenter following application of a minor and major load is measured.

The Shimana SHBLHT237 is a new microprocessor-controlled digital bench Rockwell hardness tester that offers easy, automated testing procedures and provides highly sensitive and accurate readings. It accommodates all types of hard or soft metals and alloys — carbon steel, alloy steel, cast iron, nonferrous metal, engineering plastic, etc. — in numerous configurations. The tester allows users to set upper and lower limits with visible and audible alarms, and provides data statistics, programmable scale conversions, dwell times and load cycle. In addition, it can automatically store 500 items of test results. Measuring results can be digitally displayed, printed or transmitted to an external computer automatically. 

The Shimana SHBLHT237 meets the ISO 6508-2, ASTM E18 and BS EN ISO6508-2 standards.

It is available in Canada from Digital Measurement Metrology (DMM). The Brampton, Ont.-based company offers onsite installation, training and ISO 17025 accredited calibration for this tester and other makes of hardness testers, including Mitutoyo, Newage or Starrett.
