Thermal imager

Wednesday, 27 May, 2009 | Supplied by: Testo Pty Ltd

The testo 880 thermal imager, which comes in three different versions, is being used to increase efficiency in buildings. The imager can be used for building thermography to see where heat is being leaked from a building’s insulation. With this knowledge users can maximise the efficiency of the heating system, by minimising heat loss.

With roughly 20,000 measurement values, exactly 160 x 120 pixel data resolution interpolated to 320 x 240 pixel, the imager allows reliable diagnoses on a display. The visibility of even the smallest temperature differences is ensured by germanium optics for efficiency in the infrared. With electronics for optimum use of the detector, and a thermal resolution between pixels [NETD] of less than 0.1 °C, the imager provides high-definition images.

The standard 32° wide-angle lens can be interchanged with a 12° telephoto lens offering the necessary flexibility for adapting the test thermal imager to the dimensions and distances of different subjects. For operation in tough conditions, an IR protective glass, which is made of germanium, shields the lens from dust and scratches.

The imager offers a low minimum focus distance of 10 cm for small objects and a built-in digital camera with power-LED lighting allowing real image photography to complement the IR recordings.

Linked using an image-in-image function, the system facilitates fast, secure and easy documentation. The presentation of surface moisture using dynamic humidity measurement and calculation of the parameters is used for the fast localisation of mould risk spots.

Administration of the data is possible either in the camera or via a PC using the included software. Testo thermal imager software allows analysis possibilities and easy report creation.
