Damage to the detector!
During operation, this instrument must not be pointed at the sun or other
intensive sources of radiation (e.g. objects with temperatures exceeding
650 °C). This can cause serious damage to the detector. The manufacturer
does not provide any warranty for any such damage to the microbolometer
detector.

Product description
Use
The testo 883 is a handy, robust thermal imager. You can use it to undertake
the non-contact measurement and display of surface temperature distribution.
Areas of application
• Preventive maintenance / servicing: Electrical and mechanical inspection of
systems and machines
• Building inspection: Energy efficiency rating of buildings (heating, ventilation,
air-conditioning trade, building engineers, engineering firms, experts)
• Production monitoring / quality assurance: monitoring of production
processes
- White characters: temperature margin of the
image displayed, showing the
minimum/maximum reading (with automatic
scale adjustment) or the set

M - manual scale adjustment
Power supply
The power is supplied to the instrument via a replaceable rechargeable battery
or the mains unit provided (battery must be inserted).
With an attached mains unit, power is supplied automatically via the mains unit
and the rechargeable battery is charged (only at ambient temperatures from 0 to
35 °C).
It is also possible to charge the battery using a charging station (accessory).
To maintain system data during a power interruption (e.g. when changing the
battery), the data is stored temporarily.
The camera is delivered without a battery inserted. The rechargeable
battery is supplied separately and must first be unpacked and inserted
in the camera.

Detector may be damaged!
- Do not point the camera at objects with temperatures > 650 °C.
Ideal framework conditions
Building thermography, investigating the building shell:
Considerable temperature difference between inside and outside required
(ideal: ≥ 15 °C / ≥ 27 °F).
Consistent weather conditions, no intensive sunlight, no precipitation, no
strong wind.
To ensure maximum accuracy, the camera requires an adjustment time of
15 minutes after it is switched on.
Important camera settings
• Emissivity and reflected temperature must be set correctly in order to
precisely determine the temperature. Subsequent adjustment is possible via
the PC software, if required.
• When auto-scaling is activated, the colour scale is continuously adjusted to
the min./max. values of the current measurement image. This means that
the colour assigned to a specific temperature is changing constantly! To be
able to compare multiple images based on the assigned colour, scaling must
be set manually to fixed values, or must be subsequently adjusted to uniform
values using the PC software.

SiteRecognition
With the PC software testo IRSoft QR Codes, markers can be set to clearly
identify a measuring location. By setting a marker with the built-in digital imager,
the images, which are then saved, are automatically allocated to the relevant
site (allocation is saved with this image). For the creation of markers,
transferring of measuring site data to the imager and copying of images to the
PC software, see instruction manual for the PC software.
Saved images can be displayed, analyzed or deleted. You can listen to and also
record a voice annotation subsequently or do it again.

Emissivity information:
The emissivity describes the capability of a body to emit electromagnetic
radiation. This is material-specific and must be adapted for correct
measurement results.
Non-metals (paper, ceramic, gypsum, wood, paints and coatings), plastics and
food have high emissivity, which means that the surface temperature can be
easily measured using infrared.
Because of their low or non-uniform emissivity, bright metals and metal oxides
only have limited suitability for infrared measurement. Highly inaccurate
measurements should be expected. A remedy for this is coatings that increase
emissivity, e.g. paint or emission adhesive (accessory: 0554 0051), which must
be applied to the object to be measured.
The following table gives typical emissivities of important materials. These
values can be used as a guide for user-defined settings.
Using this offset factor, the reflection is calculated out based on the low
emissivity, and the accuracy of the temperature measurement with infrared
measuring instruments is improved. In most cases, the reflected temperature is
identical to the ambient air temperature. Only when objects with strong
emissions at much lower temperatures (such as cloudless skies during outdoor
readings) or much higher temperatures (such as ovens or machines) are in
proximity to the object being measured should the radiation temperature of
these sources be determined and used. The reflected temperature has little
effect on objects with high emissivity.
@ Further information can be found in the Pocket Guide.
If it is not physically possible to determine the emissivity due to the
same object temperature and reflected temperature, the input field
opens again. The emission value must be input manually.
Position the imager so that the marker is inside the position frame.

SuperResolution
SuperResolution is a technology to improve image quality. For each shot a
sequence of images is saved in the thermal imager. Using the camera, App, or
PC software, an image is recorded with four times more measurement values
(no interpolation). The geometric resolution (IFOV) is improved by a factor of
1.6.
To use the function, the following conditions must be fulfilled:
• The camera is hand-held.
• The objects to be imaged do not move.
Save JPEG
Infrared images are saved in BMT (image with all temperature data) format. The
image can also be saved in JPEG format (without temperature data) at the
same time. The image content corresponds to the infrared image shown on the
display, including scale display and image marks for the selected measuring
functions. The JPEG file is saved under the same file name as the associated
BMT file and can be opened on the PC, even without using the IRSoft PC
software.
Using the protective glass protects the optics from environmental
influences such as dust, scratches, etc. When the protective glass is
