Material Testing

The James Instruments Pull Test, is used to measure the bond strength or tensile strength of concrete, asphalt, tile, concrete repair, or other overlay material by the direct tension or pull off method.

• Accurate bond strength of repair mortars, epoxy resins, laminates, overlays, and other coatings
• Calibrated gauge with maximum load indicator and mechanical damping
• Ball Joint Design for rapid testing as well as assuring direct tensile loading
• Adjustable alignment plate with built in leveling facility for both vertical and horizontal pulls

The James Instruments Low Impact Digital Rebound Hammer Basic System, has a number of specialized applications. It is typically used for thin concrete specimens between 50mm (2") and 100mm (4") thick, such as sidewalks, bridgedecks and some driveways. The unit can be used on plaster and morar as well to verify consistancy. The Test Hammer is also used on brittle rock cores where a larger impact will damage the specimen.

• Low impact energy ideal for brittle specimens (0.735 Nm)
• Minimum verifiable strength is 1400 psi (10 MPa) to 9000 psi (62 MPa)
• Paper and film testing are a significant application for the low impact manual test hammer
• Integrated alpha numeric digital display, and control panel
