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

The James Instruments Manual Rebound Hammer, is the traditional instrument used for the non-destructive testing of hardened concrete. This easy-to-use instrument provides a quick and simple test for obtaining an immediate indication of concrete strength in various parts of a structure.

• Impact energy level of 1.6 ft. lbs. (0.225 kg)
• Minimum verifiable strength is 1400 PSI (10 MPa) to approximately 9000 PSI (62 MPa)
• Quick and easy determination of the strength of concrete
• Manual calculation of the mean rebound number
• Conforms to ASTM C-805

The James Instruments Windsor HP Probe System, is designed to evaluate the compressive strength of concrete. The system rapidly and accurately determines the concrete compressive strength of a structure by driving a probe into the concrete with a known amount of force; the shallower the depth of probe penetration, the stronger the concrete.

• New electronic measuring system enhances accuracy and efficiency
• Non-destructive and can be used with equal effectiveness on fresh and mature concrete
• Measurement to 17,000 psi (110 MPa)
• Memory for data storage and uploading to PC
• Does not allow for accidental discharge (even when dropped) and does not have recoil

The James Instruments Windsor Pin Test System, is used to measure the strength of new or existing construction materials in-situ utilizing the established principle of resistance to penetration.

• Portable and completely self-contained
• Test new concrete products and structures for early strength
• Evaluate the in-situ strength in existing structures, e.g., after suspected fire damage
• Test strength of block, brick, and mortar joints within an existing structure, e.g., load bearing walls
• Test polymer concrete and patching compound
