Durable Rebound Hammers from Humboldt
Concrete rebound hammers are used to determine in-place strength of concrete and determine the surface hardness using the rebound principle. All models accurately measure compressive strength, which directly determines the load-bearing capacity and durability of concrete structures. Testing can be done at any angle, but calibration of the instrument must be done in the testing position. All hammers also include a grinding stone, carrying case and instruction booklet with conversion charts.
The new technology being used for rebar location is Ground Penetrating Radar or GPR. GPR is a non‑destructive testing method providing a continuous cross-sectional profile of your subsurface features. This profile is created by sending radar pulses through the test surface. The waves get refracted or reflected back to the testing device as they encounter items buried beneath the surface and the cross-sectional profile is formed.
The Quantum Mini Concrete Scanner provides a dual frequency antenna, which improves the accuracy and depth range of the unit. With the benefits of deep lower frequency 1000 MHz antenna and a high resolution 2000 MHz antenna in a compact form factor, the Quantum Mini is suitable for ALL concrete scanning applications.
We also carry a complete selection of conventional rebar locators, like the easy-to-use Profoscope, which can determine rebar diameter to a depth of 64mm. The Profometer 600 is the ideal instrument for contractors who need to avoid damages to the reinforcement steel when drilling, coring or cutting.
Another effective non‑destructive testing method for determining the quality of concrete is Ultrasonic Pulse Velocity, or UPV. Ultrasonic testing is conducted by passing a pulse of ultrasonic waves through the concrete to be tested and measuring the time taken by the pulse to get through the structure. Ultrasonic testing devices can be used to detect the presence of cracks, voids and other imperfections in concrete, as well as determine and monitor the strength and deterioration of concrete which may have occurred due to age, fire, frost or chemical attack.
Humboldt offers a full range of ultrasonic testing equipment, including the new, H-2880 Concrete Thickness Gauge. Other items like the Resipod Resistivity Meter and the various Pundit ultrasonic devices. We also have the Cross Hole Ultrasonic Monitor (CHUM) and a Sonic Echo Foundation Tester among our large product offering.
