Product Description

PTC has redesigned their entire line of analog pencil style durometers. The durometers feature a shorter barrel for improved grip and a more accurate precision ground mainspring.

The PTC Analog Pencil Style Durometers are manufactured to meet or exceed current ASTM D2240 specifications and designed to measure the indentation hardness of rubber, elastomers, and other rubber like substances such as neoprene, silicone, vinyl, nitrile, and butyl. They can also be used for soft plastics, felt, leather, and similar materials.

The durometer’s ½ inch diameter base is the smallest base permitted by ASTM D2240 specifications. This allows it to be used in confined or hard to reach areas other durometers cannot test.

The instrument uses a dial gauge with a full 360º scale and bold, easy to read numbers. The dial scale can easily be read to ½ point accuracy. A standard maximum reading hand holds the peak reading until reset.

The dial has a ‘red zone’ to indicate unreliable readings. Readings in this area should not be reported for either Type A or D. The durometer should be used in a near vertical position, but will hold tolerance up to 90º.
