1. Industry Pain Points

With the rapid economic development, the scale of various construction projects has been expanding. However, affected by multiple factors in design, construction, and subsequent use, buildings often suffer from defects such as external wall hollowing, internal liquid leakage, and poor air tightness, which bring significant potential safety hazards to the overall stability of the building structure. Traditional inspection and evaluation are usually inefficient, only capable of detecting obvious defects, surface defects, or large-area hidden defects. Nevertheless, most defects are not obvious and can only be identified after causing serious damage, which then requires high reconstruction costs. As a preventive maintenance diagnostic technology, infrared thermal imaging technology does not require physical contact with roofs, ceilings, walls, or floors. It can also inspect inaccessible areas and present the condition of a large area in a single thermal image, making it an extremely economical and non-damaging disgnostic method for buildings themselves.

2. Why Can Infrared Thermal Camera Be Used for Building Inspections?

The heat capacity of normal parts of a building is inconsistent with that of damaged parts. Therefore, when the ambient temperature changes, the rate of temperature change damaged parts differs from that of normal parts. Infrared thermal cameras can visualize the temperature distribution of objects, featuring high sensitivity, fast detection, and no need for illumination. They accurately locate abnormal positions of buildings, improving the accuracy, efficiency, and rationality of inspections, and making building non-destructive testing (NDT) more scientific and practical. Additionally, the equipment is lightweight and portable, making it an ideal tool for building inspections.

3. Advantages of Infrared Thermal Imaging in the Construction Industry

1) Non-contact and Long-distance Inspection: No damage to the building structure, no need to set up scaffolding.

2) Fast and Comprehensive Inspection: Enables rapid, thoroughreal-time scanning and imaging of buildings.

3) Intuitive and Visual Inspection Results: Two-dimensional infrared thermal imaging intuitively displays the temperature field at each point of the measured object, accurately locating defect positions and showing the size of defect areas.

4) Comprehensive Functions of Intelligent Temperature Analysis Software: Facilitates further temperature analysis of images on computers.

5) Accurate Measurement: Inputinformation such as target distance, target emissivity, and ambient temperature to automatically calculate and correct the impact of atmospheric transmittance and target surface emissivity on measurement results.
