Langry Pull-off Tester LR-P40 is designed for assessing concrete strength in both newly constructed and existing buildings, covering a strength range from C10 to C80. The device is equipped with accessories for the Post-anchoring method and After-loading and pulling-out method, providing versatility in concrete strength testing.

The underlying principle of concrete compressive strength testing involves measuring the pull-out force of anchoring elements within the concrete to estimate its strength. This instrument features a digital display for pressure values and an automatic peak-holding function, ensuring convenience during testing. The machine allows for data storage throughout the testing process, making it user-friendly and efficient.
