James Instruments specalises in Non-Destructive testing equipment for concrete and other construction materials. Central to the improvement of the concrete infrastructure are tools that evaluate the condition of existing construction.

James Instruments Inc. is the leading manufacturer of non-destructive test equipment for construction materials, specifically concrete, ceramic, wood, masonry, mortar, gypsum and other coarse grained materials. We supply the instruments that: measure strength, both compressive and tensile, locate rebar and other objects in concrete and masonry, determine density and analyze materials ultrasonically, analyze corrosion and, finally, determine moisture in concrete and other construction materials. And more. James Instruments -- rugged, quality equipment for field use -- backed by factory service and an ongoing program of research and development.
