James Digital Test Hammers
Digital hammers for the quick and easy determination of the strength of concrete
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.
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 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. USB Connection to a personal computer is via the USB interface.
