James Digital Test Hammer
model W-D-2000, W-D-1700 and W-D-1500


Digital hammers for the quick and easy determination of the strength of concrete
Application: Rapid estimate of concrete strength

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. Connection to a personal computer is via the RS-232 interface.

Calibration Anvil Model W-C-7312
It is recommended that calibration of the test hammers be checked regularly - usually after about 2000 strokes. The James Calibration Anvil (W-C-7312) has been designed for just that purpose. The Calibration Anvil weighs approximately 35 lbs. (16kg) and should be ordered separately.
