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.

Specifications:

• Measuring range: 10~70MPa
• Impact energy: 2.207J（0.225Kgf.m)
• Spring extension: 2.95inch/75mm
• Static friction of pointer slider: 0.5N~0.8N
• Radius of spherical tip : 25mm±1mm
• Average rebound values on steel anvil: 80±2
• Material: Stainless Steel
• Dimension: 60 x 280mm
• Weight: 1.0kg
