Concrete Rebound Hammer QualiCRH-2000A

Concrete Rebound Hammer QualiCRH-2000A is designed for non-destructive testing of concrete structures. This method offers significant benefits over traditional approaches to evaluating compressive strength, as it allows large areas to be tested quickly and at low cost.

The QualiCRH-2000A is comparable to the Schmidt Hammer, Type N. This testing method complies with EN 12 504-2, ASTM C805, DIN 1048, and BS1881 Part 202. These standards define the evaluation of rebound hardness in concrete, which is directly linked to the material’s compressive strength.

Steel Anvil

To ensure the test hammer remains in good working condition, it should be calibrated regularly.

  • Steel core hardness: 60 ± 2 HRC
  • Rebound value range: 80 ± 2
  • For test hammers with impact energy of 0.735 J and 0.196 J, the calibrated value should be 74 ± 2

A Guide to Concrete Rebound Hammer Calibration

A Guide to Concrete Rebound Hammer Calibration
Using a concrete rebound hammer without first verifying its calibration can lead to unreliable measurements. In construction and structural assessment, non-destructive concrete testing tools are essential for evaluating materials on-site without causing damage. The rebound hammer is a cornerstone of this toolkit because it provides a quick indication of concrete hardness. However, this speed is only useful if the data is sound. To ensure the
How to Choose: Mechanical vs Digital Concrete Rebound Hammer

How to Choose: Mechanical vs Digital Concrete Rebound Hammer
Getting an accurate picture of concrete strength on-site can be a serious challenge. A quality rebound hammer is the go-to piece of equipment for any professional who needs clear, immediate information, and the choice often comes down to a mechanical vs digital rebound hammer. That said, the most frequent question we field is about the digital vs mechanical rebound hammer choice. Do you stick with the classic, famously tough mechanical models, or

How to Correctly Use a Concrete Rebound Hammer
Getting dependable strength data from concrete on a job site isn't about the tool itself, but about how you use it. The concrete rebound hammer is an excellent instrument, but the numbers it gives are only as good as your technique. Since the hammer works by measuring the bounce-back from a quick impact, small details in your procedure can significantly change the results. This guide is focused on showing you the correct, professional way to use
