Hardness Testing

PosiTector® Shore Hardness Durometer


The PosiTector SHD measures the indentation hardness of non-metallic materials such as polymers, elastomers and rubbers. In the corrosion industry, durometers are commonly used to ensure proper curing of pipeline repair wraps.


Shore A - for soft to hard materials such as soft rubber, elastomers, neoprene, silicone, etc.)

Shore D - for medium to extra hard materials such as hard rubber, epoxies, hard plastics, PVC, acrylic, etc.
