C380   C380 Concrete Matest test hammer MPA diagram Concrete test hammer classic model

Spring impact energy 0,225 mkg.(2,207 Joule) 

The device dedicated to measure the 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. Conversion tables allows to deduce the compressive strength from the rebound value.

This non destructive testing method is safe for the structure of the concrete and allows to examine its hardness accurately. It is the top quality test hammer available on the market.

Supplied complete with calibration curve chart in N/mm 2 (Mpa) values, abrasive stone, carrying case.

Dimensions: 330X100X100 mm
Weight: 2 Kg C380
C380-01   C380-01 Concrete Matest test hammer PSI diagram Concrete test hammer ASTM Model

Exactly the same to model C380 - Matest's concrete hardness tester sold and calibrated by Macben - but the calibration curve chart shows the resultats in PsI values as requested by ASTM C805 Specifications.

C382   C382 Schmidt test hammer Standard Schmidt test hammer N

Oryginal Schmidt concrete test hammer type N: 

The high quality concrete test hammers are the most widely used portable NDT measuring instruments for a rapid assessment of the condition of a concrete structural components. Each hammer is designed for specific test applications.

In type N the rebound values are read directly from the scale. Testing the compressive strength of a prefabricated concrete girder. Rebound values are recorded by the technician who will calculate mean values and read compressive strength values from a conversion diagram. The device allows to test a wide variety of materials and types of structure like concrete, rocks ect.

C386M   C386M Digital concrete Matest test hammer Concrete Digital Test hammer Matest

This digital concrete test hammer manufactured by Matest
performs basic concrete testing with continuous automatic recording of all parameters in accordance with EN 12504-2 specifications.

Standards: EN 12504-2, DIN 1048, ASTM C805, Uni 9189, BS 1881:202, NF P18-417

The device determined to measure hardness of the concrete.The device consists of the standard mechanical model C380, but equipped with an electronic transducer that measures the rebound values and supplies automatically the results on a graphic display. The results of the test are registered and available to transfer them to a PC for further analysis. The device allows to automatic conversion of rebound index to equivalent compression strength in psi, N/mm2, kg/cm2

Measuring test performing:
- Shows index value
- Shows average index value
- Allows to select measuring system in MpA or Psi
- Shows numbers of performed rebounds
- Shows date and time
- Identifies tested element
- Identifies automatically and shows rebound angle
- Shows battery life
