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. Destructive and non-destructive testing (NDT) techniques are applied. Destructive tests can provide direct information, but are relatively expensive, time-consuming and cause damage to the structure. Destructive test results often cannot be evaluated using statistical approaches because the number of locations in the structure that can be tested without damage to the structure is limited. On the other hand, NDT techniques are relatively inexpensive to apply, and they can detect, localize, and characterize flaws and damage in concrete, wood and other construction material structures without leaving any undesirable discontinuities or causing damage to concrete members.

James Instruments supplies 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.
