Measuring range 10 to 70 N/mm2 compressive strength.
Rebound values are recorded as a bar chart on a paper strip.
One roll of paper strip offers room for 4000 test impacts.
Case Dimensions: 325 x 295 x 105mm
(Similar for all types)
Smooth test area with a grinding stone.
Perform test series of at least ten test impacts.
The compressive strength of the concrete is read from a conversion chart.
The recording strip is used as a test document. Mean rebound value R may be visually estimated.
