James Instruments Inc. Test Well Build Well! James Instruments Inc. specialises in Non-Destructive Testing equipment for concrete and other construction materials. Central to the improvement of the construction 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, Non-Destructive Testing (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 Inc. is the leading manufacturer of non-destructive test equipment for construction materials. Specifically we design, manufacture and sell the most advanced equipment to test 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 Inc. -- rugged, quality equipment for field use -- backed by factory service and an ongoing program of research and development.
