Purchasing Notes


Product Information

James Instruments™ digital test hammers are an advanced, completely automated system for estimating concrete compressive strength. Its calculation, memory and recording functions allow for quick, easy and accurate test results. The unit is also used on rock cores, it's low impact energy not damaging brittle specimens. 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. The minimum verifiable strength is 1400 PSI (10 MPa) to approximately 9000 PSI (62 MPa). All concrete test hammers measure the surface hardness of the material they are testing; this is then correlated to concrete compressive strength.

Discard values for multiple test results can be set; the mean, median and compressive strength can also be calculated. The addition of modern microprocessor technology allows the data to be stored, printed and transferred to a personal computer for further analysis, or inclusion in your reports.

The Low Impact Test Hammer 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. These units are commonly used to classify rock cores and brittle rock specimens. Finally, it is also suitable for paper and film rolls where the larger impact energy of a standard hammer will damage the surface of the material being tested.

Paper and Film testing are a significant application for the Low Impact Manual Test hammer. Typically eight to ten readings are taken across the surface of the paper or film roll to determine if the edges are as tightly wound as the center, and that winding has been even through out. TAPPI specifies readings 25mm-75mm ( 1"-3" ) from the edge and 150mm ( 6" ) down the length of the roll. Rolls too loosely wound, or to soft will go out of round during shipment and storage. This will cause unwind speeds to be slowed thereby lowering productivity. Rolls that are wound too tightly or hard can burst or tear during transport, and storage.

The unit comes with an integrated alpha “ numeric digital display, and control panel. You can switch between standard or metric units.

The field printer mounts on the belt for ease of use. Connection to a personal computer is via the USB interface.
