Infrared (Thermal Image) Survey

Thermal Image survey uses an infrared camera to detect precise temperature difference within the survey objective area. Interpretation of the thermal image will indicate various faults and areas for investigation. The practice is undertaken using "Standard Test Method for Detecting delaminating in Bridge Decks and other structures using Infrared Thermography to ASTM D4788-88 and Building Safety Inspection Scheme (BSIS) standard that is widely use overseas and now in Hong Kong.

Scope of Surveys:

1. Building External Wall – detection of voids caused by delaminating.
2. Detection of water pipe leakage.
3. Heat Exchanger Tube Bundle leak detection.
4. Power cable leak detection and faulty connections for preventive maintenance.
5. Detection of termites, vermin or any traceable heat generating pests or objects.

Equipment Details:

1. "Fluke FlexCam Ti55FU" Thermal Imaging Camera with 35 & 55mm lens.
2. IRISYS 1010 Infrared Thermal Image handheld unit.
3. Nikon D40X digital camera with 15-55mm; 55-200mm lens.
