| Equipment: Schmidt Hammer |
|
Model: ORIGINAL SCHMIDT |
|
Features |
- Type N: Rebound values are read from a scale for
subsequent calculation of the mean. Compressive strength
values can be read from a conversion diagram
- Type NR: Rebound values are recorded as a bar chart
on a paper strip which has a capacity for 4’000 test impacts
- Type L: Handling equals type N, but the type L offers an
impact energy three times smaller
- Type LR: Handling equals type NR, but with impact
energy three times smaller. The LR also features a paper
strip enabling up to 4’000 test impacts without reloading

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
