The lenses listed in the table above can be used interchangeably with the Testo 890 Thermal Imaging Camera. They adapt the camera for various applications:

  • 42° x 32° Standard Lens: provides a large field-of-view making the Testo 890 Thermal Imaging Camera ideal for inspecting closer objects
  • 25° x 19° Standard Lens: ideal for preventative maintenance applications
  • 15° x 11° Telephoto Lens: capture clear images of objects at a medium or long distance from the Testo 890 Thermal Imaging Camera

Furthermore, the Testo 890 Thermal Imaging Camera’s auto-focus ensures that it is always able to capture sharp images. This function also facilitates one-handed operation of the camera. The Testo 890 Thermal Imaging Camera has a minimum focus distance of 10cm.

Thermal Imaging

A thermal resolution of 640 x 480px provides 307 200 measurement points. Inclusion of SuperResolution technology means the Testo 890’s thermal resolution can be increased to 1280 x 960px. Moreover, the Testo 890 Thermal Imaging Camera has a thermal sensitivity of <40mK which enables detection and visualisation of small temperature differences.

Thermal images can be saved as JPEGs to the Testo 890 Thermal Imaging Camera’s SD card. Voice annotations can be added to these images using the supplied headset. Additionally, digital images, captured using the Testo 890 Thermal Imaging Camera’s integrated visual-light camera with power LEDs, can be saved with thermal images to improve the ease of documentation and assignment.

The Testo 890 Thermal Imaging Camera’s SiteRecognition technology also improves the ease of documentation: it instantly recognises locations and automatically assigns and archives footage according to the identified place.

Testo IR Soft Professional Software

Saved footage can be downloaded to a PC for analysis using Testo’s IR Soft Professional Software (free download). Using this software, thermographers can do the following:

  • Correct emissivity
  • Set an unlimited number of measurement points
  • Identify hot and cold spots
  • Add written notes
  • Highlight areas that exceed permissible limits
  • Create reports

Imaging & Measurement Functions

The Testo 890 Thermal Imaging Camera also features the following imaging and measurement functions:

  • Panorama Image Assistant: images are combined into a panoramic picture enabling entire buildings to be inspected quickly as individual images do not have to be compared or compiled.
  • Mould Measuring mode: the ambient temperature and humidity are manually entered into the Testo 890 Thermal Imaging Camera to calculate dewpoint; the surface temperature, measured by the Testo 890, is compared to this value to determine the risk of mould which is indicated using a traffic light system; an OPTIONAL radio humidity probe can be used to transfer ambient temperature and humidity readings to the Testo 890 automatically.


In addition to the above, the Testo 890 Thermal Imaging Camera can be purchased with the following OPTIONAL features, functions and packages:

  • FeverDetection function: identify individuals with elevated skin temperature
  • High-temperature measurement: extends the temperature measurement range up to 1200°C
  • Process Analysis Package: record radiometric thermal footage to a PC at 33Hz and log data for up to three points of the image; please see the videos below for further information


The Testo 890 Thermal Imaging Camera’s camcorder design with a wrist strap and rotatable, fold-out display facilitates single-handed operation and a wide range of camera angles.

The Testo 890 Thermal Imaging Camera is a simple-to-use, adaptable and practical infrared imager with a high thermal resolution. It is ideal for a range of electrical, mechanical, building, and industrial applications.
