Measuring range 10 to 70 N/mm2 compressive strength.

With a three times smaller impact energy than type N.
The impact plunger tip is a special design.

This type is used for fired clay products.

Supplied in a carrying case including a grinding stone and operating instructions.
Case Dimensions: 325 x 125 x 140mm
Weight: 1.4kg

Test Procedure

(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.
