• Accurate results to within approx. 15% on 1,250 to 8,500 psi concrete.
• Calibration curves plot the hammer rebound number versus compressive strength.
• Lightweight and portable.
• Carrying case and instructions included.
The Concrete Test Hammer is used as a control and test instrument for measuring the quality and strength of in-place concrete. This quick and inexpensive instrument is not intended as a substitute for control testing of concrete cylinders. The Concrete Test Hammer is valuable for use in the field for trouble-shooting to determine when test cores are needed and where they should be drilled.
