2.2. Ensure safety
> Only operate the product properly, for its intended purpose and
within the parameters specified in the technical data. Do not
use any force.
> Do not operate the instrument if there are signs of damage at
the housing, mains unit or feed lines.
The thermal imager must not be directed at the sun or other
sources of intense radiation (e.g. objects with temperatures greater
than 500 °C, 800 °C while using the high-temperature filter) during
operation. This may lead to serious damage to the detector. The
manufacturer accepts no warranty for this type of damage to the
microbolometer detector.
> The objects to be measured or the measurement environment
may also pose risks: Note the safety regulations valid in your
area when performing the measurements.
> Do not store the product together with solvents. Do not use any
desiccants.
> Carry out only the maintenance and repair work on this
instrument that is described in the documentation. Follow the
prescribed steps exactly. Use only original spare parts from
Testo.
> Improper use of rechargeable batteries can lead to destruction
or injuries by means of current surges, fire or escaping
chemicals. The following instructions must be observed to avoid
such hazards:
• Only use in accordance with the directions in the instruction
manual.
• Do not short, take apart or modify.
• Do not expose to heavy impacts, water, fire or temperatures
above 60 °C.
• Do not store in the proximity of metal objects.
• Do not use leaky or damaged rechargeable batteries. In the
event of contact with battery acid: Thoroughly wash affected
area with water and consult a doctor, if necessary.
2 Safety and the environment

• Only charge in the instrument or the recommended charging
station.
• Immediately stop the charging process if this is not
completed in the given time.
• In the event of improper function or signs of overheating,
immediately remove the rechargeable battery from the
measuring instrument/charging station. Caution:
Rechargeable battery may be hot!
2.3. Protecting the environment
> Dispose of faulty rechargeable batteries/spent batteries in
accordance with the valid legal specifications.
> At the end of its useful life, send the product to the separate
collection for electric and electronic devices (observe local
regulations) or return the product to Testo for disposal.

3.1. Use
The testo 882 is a handy and robust thermal imager. It opens the
door to contactless determination and illustration of the temperature
distribution on surfaces for you.
Typical areas of application are:
• Building inspection (heating, ventilation and air conditioning
trade, company technicians, engineering offices, experts):
Energy evaluation of buildings
• Preventative maintenance (servicing): Mechanical and electrical
inspection of systems and machines
• Production monitoring (quality assurance): Monitoring
production processes
Basic properties:
• High-quality wide-angle lens 32° x 23°, detector 320 x 240,
NETD < 60 mK, 2 GB SD card for approx. 1000 images,
minimum focus distance 20 cm, integrated digital camera with
power LEDs for illumination, dynamic motorfocus, isotherm,
min./max. on area, audio comments, display of surface moisture
distribution, high-temperature filter (optional)
Export control
Thermal imagers may be subject to the export restrictions of the
European Union.
The testo 882 with 33 Hz in particular can only be exported to
countries outside of the European Union with an export permit from
the authorities.
Please observe the national regulations for export control when
exporting.
