The 408 case tapers to a 1 x 1 base to allow better access to confined areas. A removable top knob permits both easy hand held use or attachment to test stands.
The Model 408 Type A Durometer is designed to measure ASTM (American Society for Testing and Materials) Type A hardness. This includes materials such as: rubber, elastomers, and other rubber-like materials including neoprene, silicone, vinyl, and butyl. Soft plastics, felt, leather, and similar materials generally fall into this same range. PTC® s Model 408 meets or exceeds current ASTM D2240 Specifications.
Accurate readings can be
obtained in any position.
These durometers can be used either with a
, hand-held or with the constant load weight model 441.

May the Force Curve be with you...
For a complete calibration check of mainspring, and visual and mechanical check of indenter, the instrument should be returned to PTC® (see Guarantee & Calibration Service) or refer to ASTM D2240 Specifications. PTC® recommends the
unit be returned at least every 12 months for this check. For a quick field check, follow the guideline below. Under no circumstance should a test block be used as a standard to calibrate a durometer.
1. The pointer should read zero when no force is applied to the indenter of the durometer.
2. Hand hold the durometer and insert the indenter into the hole of the calibrated test block. Apply enough force to make firm contact between the top surface of the test block and the base of the durometer. The dial reading should agree with the value stamped on the check block (±1). Several tests should be made and the results averaged.
3. The indenter must protrude 0.098 to 0.100 inches below the base of the durometer.
4. When the indenter is fully displaced, the durometer should read 100 points. Use care as to not damage the tip of the indenter.
