testo 890 - Thermal imager with one lens

  • testo 890 professional thermal imager: resolution 640 × 480 pixels, upgradable to 1280 × 960 pixels with SuperResolution technology, thermal  sensitivity < 40 mK
  • Choice of lens between standard, 25° and telephoto lens – you are free to choose one lens
  • Sequence capturing in the instrument a possible option, humidity  calculation, SiteRecognition, panorama image assistant, JPEG storage  function and other practical features
  • Integrated digital camera, optionally  exchangeable lenses, many more features, large scope of delivery  including transport case, memory card, professional software, etc.                

The testo 890 thermal imager means you are ideally equipped both for professional industrial thermography and for building thermography: e.g. for inspecting voltage systems, high-temperature measurement, circuit board analysis, control of solar plants, complete building shell  thermography and building thermography for energy consultancy.

The testo 890 professional thermal imager means you are ideally equipped for the following applications:

  • Safe high-temperature measurement
  • Analysis of building shells at a glance
  • Regular checks in electrical maintenance
  • Precise visualization of critical temperatures on circuit boards
  • Carrying out detailed energy consultancy
  • Analysis of energy distribution systems

All the important information about the testo 890 thermal imager

  • Up to 307,200 temperature measuring points: a detector size of 640 x 480 pixels guarantees accurate detection. SuperResolution technology even boosts image quality to 1280 x 960 pixels!
  • Thermal sensitivity < 40 mK: even the smallest temperature differences can now be seen
  • You can also choose to save thermal images as JPEGs
  • Process analysis package (optional): the combination of fully radiometric video and sequence capturing in the camera enables wireless measurement and easier handling at the measuring location
  • The camcorder design with wrist strap, along with the rotatable, fold-out display, makes taking images considerably easier. This makes it possible for a wide variety of camera angles, as well as one-hand operation
  • Panorama image assistant: individual images are combined into a panoramic image as soon as they are taken. This means, for instance, that you can take thermal images of entire building shells without having to laboriously compile them or assess them individually
  • SiteRecognition technology: with similar measurement objects, the thermal imager identifies measuring locations immediately, assigns them automatically and archives them accordingly
  • Optional high-temperature measurement up to 1,200°C: with the high-temperature option, the measuring range can be flexibly extended up to 1,200°C
  • Special measuring mode for detecting areas susceptible to mould: the dewpoint in the room is calculated by manually entering the ambient temperature and humidity. The surface temperature value measured by the camera is then compared to the dewpoint. The display now shows the risk of mould in traffic light colours (red, yellow, green). The optional radio humidity probe makes things easier: automatic transmission of readings means that manual input of humidity and ambient temperature is no longer needed
  • FeverDetection (optional): use the assistant to check people for high body temperature in public places and in means of transport – for public health protection
  • Voice recording (as comments on the images) possible with headset which is included in the scope of delivery
  • Integrated digital camera with power LEDs: you can take well-lit, real images to go with every thermal image - making documentation and assignment easier
  • Auto-focus for easy one-hand operation and less blurred images
  • Lens exchange possible
  • Minimum focus distance 10 cm
  • Analyze thermographic readings directly on the PC with the testo IRSoft professional software


You are free to choose one from a total of three lenses:

42° x 32° standard lens:

  • Ideal for inspecting closer measurement objects
  • Large field of view

25° x 19° lens:

  • Ideal for use in applications involving preventive maintenance

15° x 11° telephoto lens:

  • Makes it possible to take outstanding images of measurement objects at medium and longer distances
