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.
