The DTI-225 digital concrete test hammer is a type of rebound hammer used for the non-destructive testing (NDT) of concrete compressive strength.
It works by measuring the rebound of a hammer on a piston against the concrete surface.
The rebound value is then used to estimate the concrete's compressive strength.
Digital display: An OLED screen shows the rebound value and other information.
Data processing: The device automatically records, stores, and calculates compressive strength based on the rebound value.
Data connectivity: Test data can be transferred to a computer via USB or Bluetooth for further analysis and reporting.
High accuracy: It uses a non-contact, photo-coupling sensor to collect rebound values, which increases accuracy and stability.
Automatic functions: The hammer can automatically correct for the impact direction and can be set for different testing parameters on-site.
Voice reporting: Some versions may include a voice function to announce the count during on-site testing.
Durable design: The hammer is built for field use with a dust-proof structure and a robust housing.
Rechargeable battery: It is powered by a rechargeable lithium battery for long-term use in the field.
Measuring range: 10 to 70 MPa (or 1,450 to 10,152 psi).
Impact energy: 2.207 ±0.1 J (0.225 kgfm).
Dimensions: $Φ$54 x 280 mm.
Weight: Approximately 1 kg.
