During operation, the imager must not be pointed at the sun or
other intensive sources of radiation (e.g. objects with temperatures
greater than 550°C/1022°F, if using the high-temperature
measurement range 1400°C/2552°F). This can lead to serious
damage to the detector. The manufacturer assumes no liability for
any such damage to the microbolometer detector.

The testo 885 is a handy and robust thermal imager. It enables you
to carry out contactless determination and display of the
temperature distribution on surfaces.
Typical areas of application are:
•Building inspection: energetic assessment of buildings, and
inspection of heating, ventilation and air conditioning systems.
•Preventative maintenance (servicing): mechanical and electrical
inspection of systems, machines and energy distribution
systems
•Production monitoring (quality assurance): monitoring of
production processes
•Professional energy consultation, leak detection
•Checking of photovoltaic modules
The testo 885 is available in several versions, which are tailored to
various usage requirements:
•testo 885-1: high-quality wide angle lens 30° x 23, detector 320
x 240, NETD < 30 mK at 30°C, 2GB SD card for approx. 2000
to 3000 images, SuperResolution with 640 x 480 pixels
(optional), minimum focusing distance 0.1 m, touchscreen, built-
in digital imager with power LEDs for illumination, auto-focus,
isotherm, min/max/avg on area, image stitching wizard, laser
(not available in all countries), rotatable handle, rotatable and
pivoting display
•testo 885-2, additional/different functions/features: telephoto
lens (optional), super-telephoto lens (optional), display of
surface moisture distribution via manual input of the ambient
conditions (optional: humidity measurement in real time with
radio humidity probe), SiteRecognition (site recognition with
image management), voice recording, high temperature
measurement (optional), process analysis package - sequence
capturing in the camera and video measurement on the PC
(optional)
Export control
Thermal imagers may be subject to the export restrictions of the
European Union.
Please observe the national regulations for export control when

Operation via touchscreen offers quick access to functions.
Operation via joystick requires more actions but enables single-
handed operation of the imager.
Joystick operation
Selection and activation is carried out in two steps: moving the
joystick ( [●] ) up/down/right/left moves the orange selection box on
the display. The selected function or button is activated by pressing
the joystick.
