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.
During operation, testo 880 may not be pointed at the sun or
other high-radiation sources (e.g. objects with temperatures
higher than 500 °C). This can lead to serious damage to the
detector. Damage caused in this way to the microbolometer
detector is excluded from warranty coverage.
> 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 the rechargeable battery 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.
• Only charge in the measuring 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 880 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
The testo 880 is available in several versions, which are tailored
to various usage requirements:
• testo 880-1: High-quality wide-angle lens 32° x 24° with F1
lens, detector 160 x 120 interpolated to 320 x 240 pixels,
NETD < 0.1 °C, manual focus, 1 GB SD card for
approx. 800-1000 images, minimum focusing distance
10 cm, Integrated digital camera
• testo 880-2: High-quality wide-angle lens 32° x 24° with F1
lens, detector 160 x 120 interpolated to 320 x 240 pixels,
NETD < 0.1 °C, manual focus, 1 GB SD card for
approx. 800-1000 images, minimum focusing distance
10 cm, Exchangeable lens, display of surface moisture
distribution, lens protection glass included in delivery
• testo 880-3: High-quality wide-angle lens 32° x 24° with F1
lens, detector 160 x 120 interpolated to 320 x 240 pixels,
