Description:

The thermal imager testo 885 is the professional measuring instrument for the high-precision detection of anomalies and damage to building shells or interiors. The high-quality infrared measurement system means that energy losses or thermal bridges in building shells can be reliably detected, enabling comprehensive energy consultations to be carried out. Indoor leaks can be reliably located, without needing to dismantle cable or pipeline systems. The intuitive testo 885 with its rotating handle, fold-out display and lots of helpful functions, such as panorama image assistant and autofocus, makes it is possible to carry out both quick on-site checks as well as comprehensive energy consultations with professional reports simply, reliably and professionally.

 It can be used for the following measuring tasks:

  • Inspecting high-voltage lines: the super-telephoto lens enables you to inspect even the smallest of connections from a long, safe distance
  • Monitoring and checking solar plants, including locating hotspots in solar parks.
  • Detecting irregularities in large industrial plants (e.g. refineries)
  • Safe high-temperature measurement & carrying out detailed energy consultations
  • Checks in electrical maintenance
  • Analysis of building shells at a glance
  • The exact fields of application depend on the choice of second lens.
  • Process analysis package (optional): the combination of fully radiometric video and sequence capturing in the camera.
  • FeverDetection (optional): use the assistant to check people for high body temperature in public places and in means of transport – for public health protection

 

Recommended fields of application

  • Detecting structural defects and ensuring construction quality
  • Energy consulting (including building shell)
  • Leakage detection
  • Preventive maintenance
  • Research and development
  • Power generation and power distribution
