Concrete Hammer Test Type N
Type N
Measuring range 10 to 70 N/ mm² compressive strength
( Below 25 N/ mm² type P is better suited) . Impact energy = 2, 207 Nm.
Type N : Rebound values are read from a scale for subsequent calculati values can be read from a conversion diagram

Applications
Used for the non-destructive measurement of the concrete/ mortar compressive strength characteristics
Control of uniform concrete quality ( in-situ concrete and prefabricated structures)
Detection of weak spots in the concrete
The type L/ LR hammer operates with significant lower impact energy, making this hammer the ideal option for testing thin walled items with a thickness between 50 to 100 mm ( 2 in. and 4 in.) or for testing small components.
It is suitable for testing cast stone components which are sensitive to impact. In rock mechanics, the type L/ LR hammers are commonly used for classification testing of rock cores and brittle rock

Technical Data
Type N
Measuring range 10 - 70 N/ mm2 ( 1' 450 to 10' 152 psi)
Impact energy 2.207 Nm
Paper strip No
