Infrared thermal imaging detection of building exterior walls, also known as thermal image non-destructive testing (TNDT), is a non-contact detection method. Using infrared thermography to conduct large-scale detection of the detection area, which can be directly seen in the form of thermal images and recorded and displayed; By analyzing thermal images with high precision, detection conclusions can be drawn. At present, it is widely used in the detection of hollowing in exterior wall decorative layers, leakage detection of roofs and walls, pipeline leakage detection, and quality inspection of energy-saving engineering.

                      Compared with other non-destructive testing methods, infrared thermal imaging non-destructive testing has the following advantages: ① fast data display speed, ② infrared detection heat source and detector do not require physical contact with the tested object; ③ Easy to implement on-site testing; ④ Safe, non radioactive material, fast surface heating and temperature rise Do not cause damage to the detected object; ⑤ Widely applicable,

Main applications:

1  External wall decorative layer hollowing detection

2  Roof and wall leakage detection

3  Pipeline leakage detection

4  Quality inspection of energy-saving engineering

Through the application and development of infrared thermal imaging detection technology, infrared thermal imaging technology will play an increasingly important role in property management, preventing unexpected disasters and accidents, ensuring urban safety systems, and guaranteeing the quality of building energy-saving projects.
