How to Choose the Right Shore Durometer System for Your Needs

Using a reliable shore durometer system is crucial when assessing a material’s hardness. With sturdy, simple-to-use, and ergonomic equipment, NextGen Material Testing specializes in precise shore durometer systems for plastics and rubbers.

Portable Shore A Durometer

The American Society for Testing Materials (ASTM) DD2240 specifications for measuring Type A hardness include rubber, elastomers, neoprene, silicone, vinyl, butyl, and some soft plastics, felt. Leather, among others, is met or exceeded by the Model 306L Shore A Portable Durometer – Classic Style. This portable shore durometer system model includes a point dial that is simple to read and low in glare. If needed, it is also available with A2LA/NIST certification.

The Model 306L portable durometer system has all the features of the 306L model and measures to an accuracy of 1/2 point. These Shore A durometer systems allow accurate readings from any angle.

Portable durometer, Shore D

The Model 307L Shore D Portable Durometer evaluates the hardness of hard rubber, plastics, epoxies, soft metals, and other materials. It complies with or exceeds ASTM D2240 requirements for Type D materials.

This model is a reliable shore durometer system with a 1-point accuracy and the option of NIST certification. The dial is simple and low-glare, with a 0 to 100-point range.
