Concrete Test Hummers
Original SCHMIDT Test Hammer Type N:
SCHMIDT-N
Measuring range 10 to 70 N/mm² compressive strength (below 25 N/mm² type P is better suited). Impact energy = 2,207 Nm. Rebound values are read from a scale. Testing the compressive strength of a prefabricated concrete girder. Rebound values are recorded by an assistant who will calculate mean values and read compressive strength values from a conversion diagram
Original SCHMIDT Test Hammer Type NR:
SCHMIDT-NR
Measuring range 10 to 70 N/mm² compressive strength. Impact energy = 2,207 Nm. Rebound values are recorded as a bar chart on a paper strip. One roll of paper strip offers space for 4000 test impacts. A bridge concreted in several stages is tested for uniform concrete quality. The engineer will perform a series of tests in intervals of 10 m each.
Original SCHMIDT Test Hammer Type DIGI-SCHMIDT:
Measuring range 10 (ND) / 18 (LD) to 70 compressive strength. Rebound values are measured by an electronic method and may be read directly as compressive strength values.
Silver SCHMIDT Test Hammer :
SCHMIDT SILVER
Extended Range of Applications
l. Conversion curves are provided for a wide range of compressive concrete strength, including low and high strength concrete fc<10 N/mm2 (1.450 psi) and up to 170 N/mm2 (24.650 psi).
2. Conversion curves for different types of modern concrete are preset in the Silver Schmidt, based on tests performed by an independent institution.
Operation :
1. Simple operation with the "one button" user interface
2. Language independent through the use of graphic user interface
3. Automatic conversion to the required measurement unit (N/mm2, kg/cm2, psi)
4. Various statistics to comply with standards or user specified procedures
5. Custom presets of test parameters for various testing scenarios can be stored and later recalled
6. Quick review of previous measurements
PROFOMETER 5+ Rebar Detection System :
1. Location and orientation of reinforcing bars
