BS 1881:202 | NF P18-417
Designed to perform non-destructive tests on concrete structures,
it gives an immediate indication of the compressive strength of the
concrete using the calibration curve supplied with.

MODELS
C380
CONCRETE TEST HAMMER MADE IN MATEST
Spring impact energy 0.225 mkg. (2.207 Joule or Nm)
Suitable for finished concrete structures and buildings having strength
resistances from 10 to 70 N/sq.mm. This concrete test hammer,
entirely produced by Matest, has aluminium frame and thanks
to its very accurate manufacture processing and selected components
ensures high precision test results in the time.
The top quality test hammer available on the market.
Supplied complete with calibration curve chart in N/mm² (Mpa)
values, abrasive stone, carrying case.
Dimensions with the case: 330x100x100 mm
Weight: 2 kg

C380-01
CONCRETE TEST HAMMER MADE IN MATEST
Exactly the same as mod. C380, but with calibration curve chart in
PsI values as requested by ASTM Specifications.
C381
CONCRETE TEST HAMMER MADE IN MATEST
Similar to mod. C380, but with impact energy of 0.735 Joule (Nm).
Ideal to test small sized, sensitive and thin walled materials.
Suitable to test also rock core samples.

C390
ANVIL
STANDARD: EN 12504:2
Used for the verification of the
calibration of the concrete test
hammers. Special steel alloy made.
Dimensions: Ø 150 by 320 mm.
Weight: 16 kg approx.
Note:
The EN 12504:2 Specification
requires obligatory
the use of the anvil for the
hammer tests.
The Standard specifies:
– Before a sequence of
tests on a concrete
surface, take and record
readings using the steel
reference anvil and check
to ensure that they are
within the range recommended by the manufacturer. If they are
not, clean and/or adjust the hammer.
– After tests, take readings using the steel anvil, record them and
compare them with those taken prior to the test. If the results
differ, clean and/or adjust the hammer and repeat the test.
