• 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.
The hammer is intended for testing the quality of concrete in finished structures such as buildings and bridges. Supplied complete with carrying case and carborundum stone, the hammer is suitable for testing concrete with compressive strengths of 10 to 70 N/mm2.
