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.

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.

Frequently Asked Questions

Q. Unit gives low or high readings ?

A. Unscrew cap on top of unit, there is a screw in the cap. Adjust the screw up or down and check reading against test anvil.


Q. Unit will not fire when depressed ?

A. Make sure cap screw is in the proper position. Check to make sure trigger spring is present. Check for plunger spring in tip


Q. My first reading was very low, but the readings after that are consistent ?

A. Disengage hammer and let it sit before taking your first reading.


Q. How many readings should I take in one particular area?

A. You should take 10 readings, if you have any large deviation, exclude them and take additional readings.
