非破坏性
混凝土测试设备
非破坏性测试, 或无损检测, allows for inspection of concrete without damaging or altering your material in any way. NDT allows you to ensure that your critical infrastructures are properly maintained and accidents are avoided. Non‑Destructive Testing is also known as Non‑Destructive Inspection (NDI), Non‑Destructive Evaluation (NDE) and Non‑Destructive Examination (NDE).
混凝土 NDT methods not only asses concrete strength, but can also evaluate corrosion of reinforcement, 孔隙结构, 开裂与渗透性. 洪堡 provides a variety of testing instruments to enhance your inspection methods.

Durable 反弹锤子 from 洪堡
混凝土 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 探地雷达 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 项目 buried beneath the surface and the cross-sectional profile is formed.
The Quantum Mini 混凝土 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, 比如易于使用的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, 取心或切割.
超声检测
Another effective non‑destructive testing method for determining the quality of concrete is Ultrasonic Pulse Velocity, 或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, 火, 霜冻或化学侵蚀.
洪堡 offers a full range of ultrasonic testing equipment, 包括新的, H-2880 混凝土 Thickness Gauge. Other 项目 like the Resipod 电阻率 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.
Combining multiple NDT methods will improve the reliability of test results and can be essential to deciding what future repairs are required or how stable a structure is. These non‑destructive test methods are crucial to safety determinations and offer cost savings over time.
Choosing the right non‑destructive test for your application can be as simple as checking local requirements as required by law. Manufacturers may also have best practices and NDT standards available to you. 如果两者都不存在, try finding guidance by searching for industry best practices or consulting with a NDT technician.
