Principle of Operation

The Wallace Handheld Durometers are designed for measuring the hardness of various materials. Simply pressing the unit vertically onto the sample will cause the indenter to penetrate the sample under a specific spring force. The indention is converted to a hardness value.

To increase repeatability and accuracy, use the handheld unit in conjunction with the WAH18 stand. This will ensure that repeatable force and perpendicularity are maintained, thus increasing the repeatability and accuracy of each test.
