Thermal IR Cameras

The testo 875/881 thermal imagers, use infrared radiation, for conducting building, production & technical diagnostics. They can provide a full thermal picture & real images of buildings, equipment, process lines, plants, electrical systems and machines. They help pinpoint problems with ease & accuracy utilizing a non-contact imaging system.

The testo 875 and 881 IR imagers
let you actually see the heat…

• that seeps through walls, doors and windows due to poor construction, insulation or design;
• from a faulty electrical circuit about to fail or cause a fire;
• from friction in a failing bearing of a motor or compressor;
• or from the cooling created by moisture trapped in a wall or floor that starts mold growt

Kit Configurations

The testo 875 has been designed for performing building thermography by HVAC and Weatherization professionals. It is available in two versions:

  •   testo 875-1i: NETD 100 mK basic imager with manual focus.
  •   testo 875-2i: Adds an integral digital cameras

The testo 881 series has been designed for industrial thermography conducted by predictive and preventative maintenance professionals. It is available in two versions:

  •  testo 881-1: NETD < 80 Mk imager with integral digital camera.
  •  testo 881-3: Adds dynamic motor focus, protective lens, voice recording, Isotherm display, power LEDs, optional high temperature measurement (1022Ί F,

The NETD indicates the smallest possible temperature difference that can be resolved by the imager. A low NETD guarantees the resolution of the smallest temperature differences. The smaller this value is, the better the measurement resolution of the imager.
