The 408 case tapers to a 1 x 1 base to allow better access to confined areas. A removable top knob permits both easy handheld use or attachment to test stands.
The Model 408 Type A Durometer is designed to measure ASTM D2240 Type A hardness. This includes materials such as rubber, elastomers, and other rubber-like materials including neoprene, silicone, vinyl, and butyl.

Accurate readings can be obtained in any position.
The instrument has a low glare aluminum dial with bold, easy to read numbers. The durometer comes standard with a Max Hold hand, which retains the peak reading. The case tapers to a base that is 1” x 1” to allow better access to confined areas. A removable top knob (8-32 threads) permits both easy hand held use or attachment to test stands or 1 kg deadweight.
