HT-225 Digital Concrete Rebound Hammer – Portable Schmidt Tester for Strength Assessment (10–70 MPa)

Description

Concrete rebound tester is used to test the compressive strength of concrete, and it is the most widely used non-destructive testing instrument for concrete compressive strength. It has certain strength and strong fatigue resistance. Suitable instrument for testing buildings, highway and bridges.
Features:

• Center rod is made from imported material, high accuracy and durable resistance
• The shell is made form high Aluminum in order to perfect protect instrument from damage and extend use life
• Spherical zero adjustment screw: Springback is more smooth..
• Cap/Spring: It has good mechanical properties and good stability.
• Push button: With one click, it can be retractable.
• Scale: The scale is clear and the pointer is smooth.
