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

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. Customer benefits: Well made instrument with a wide range of applications Proven durability and high quality of the devices Established Proceq Swiss Made accuracy and reliability Impact Energy: 2.207 Nm Measuring range: 10 to 70 N/mm2 (1,450 to 10,152 psi) Standards: EN 12504-2; EN 13791; ASTM C 805; JGJ/T 23;JIS A 1155; ISO/DIS 8045; ASTM D 5873 (Rock) Original Schmidt Concrete Test Hammer Type N - consisting of: Impact device, carrying case incl. grinding stone, user manual and calibration certificate C382

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 Technical specifications: - Impact energy: 2,207 Joule (Nm) - Measuring range: 10 – 120 N/mm2 - Interface: RS232 - Power source: 6 rechargeable batteries AA NiMh 2000mA - Battery life: 60 hours with automatic shutdown - Operating temperature: -10°C +60°C - LCD 64 x 124 - Up to 20000 test results Supplied complete with data transfer software, data transfer cable RS232, battery charger, abrasive stone, carrying case Dimensions with case: 330x180x120 mm Weight: 3 kg C386M
