Testo 865s Thermal Imaging Camera
The testo 865s thermal imaging camera is the ideal entry into the world of thermography. It impresses with the best image quality in its class and intuitive operation in a modern tile look. The testo 865s fits comfortably in the hand and is robust enough to withstand the rigours of everyday use. Helpful functions such as IFOV-Warner and ScaleAssist ensure even better thermal images. All that combined with an unbeatable price-performance ratio. Switch on point, know more.
With a thermal resolution of 160 x 120 (19,200) pixels and a thermal sensitivity of <0.10°C, the testo 865s provides readings accurate for many day to day applications including.
- Identifying over heated breakers
- Sludge build up in radiators
- Locating faults in under floor heating
- Finding blockages in pipes
- Indicating poor insulation around doors or windows
- Detect damp or cold spots on walls and ceilings
- Pinpoint thermal bridges
The thermal resolution of the Testo 865s can is boosted to 320 x 240 thanks to SuperResolution technology. When activated, the 865 takes 4 images for each single trigger press. The images are then overlapped to produce one image with twice the thermal resolution, mimicking the resolution performance that of more expensive thermal cameras.
The testo 865s also automatically identifies hot and cold spots to instantly identify potential problems. Images can be saved as JPEGs which makes it easy to send images to clients or store for your own records. The Pro software included allows for further image evaluation should reporting by the user be required. The Pro software is free and easy to use with on screen instructions.
Another great feature of the 865s is ScaleAssist, which automatically filters undesired temperature extremes out of the image. Without ScaleAssist, extremes can mask small temperature differences which could cause issues to be missed. For example, gaps in insulation or small leaks in pipes. ScaleAssist is a feature on all Testo 870s series thermal imaging cameras.
