The thermal imager testo 865 is the ideal entry into the world of thermography. It stands out thanks to the best image quality in its class and handy operation, is robust enough to withstand tough daily use, and has useful functions for even better thermal images. And all this at a ground-breaking price-performance ratio. Switch on, aim, know more.

  • Very good image quality: IR resolution of 160 x 120 pixels, via integrated testo SuperResolution Technology 320 x 240 pixels
  • Very good measuring accuracy of ±2°C
  • Visualizing temperature differences from 0.12°C
  • Automatic detection of hot and cold spots

The testo 865 thermal imager offers professional technology and concentrates on functions that are needed in a contractor's daily work. The testo 865 is a user-friendly thermal imager, optimized for fast and efficient work. With the testo ScaleAssist functions ensuring optimum setting of the thermal image scale for building thermography and the IFOV warner making sure you avoid measurement errors, you will always generate the perfect infrared image.


Technical highlights of the testo 865 thermal imager
The testo 865 thermal imager stands out thanks to its easy operation and has the following impressive technical features:

  • Very good image quality due to high resolution: 19,200 temperature measuring points ensure precise thermography. Infrared resolution of 160 x 120 pixels – via integrated SuperResolution Technology 320 x 240 pixels
  • Visualize temperature differences from 0.12°C
  • Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
  • The IFOV warner means the distance from the measurement object/measurement spot size is determined and the measurement spot is shown on the thermal image – you, therefore, avoid measurement errors because the camera shows you exactly what you can measure
  • Pro software for image evaluation on the PC
  • You can choose to save thermal images as JPEGs


Areas of application of the testo 865 thermal imager
Detect leaks, identify overheated connections, pinpoint thermal bridges or detect structural defects. The testo 865 thermal imager is ideal for applications in daily maintenance and installation work in trade and industry. It enables time-saving quality assurance and ensures reliable production control.

Preventive maintenance
Ideal for the early identification of imminent malfunctions or defects on plants and machines: Reliably record temperature increases with a thermal imager.
 - Fast detection of critical thermal status (so-called HotSpots) during continuing operation
 - Avoid expensive damage, downtimes and fire risks on plants and machines
 - Electrical maintenance:
          Test switching cabinets, electrical conditions, photovoltaic plants
          Evaluate heat status in low, medium and high voltage plants
 - Mechanical maintenance:
          Identify wear on machines
         Test motors, bearings, shafts

Detecting structural defects and ensuring construction quality
- Detect potential building defects, prove quality and the implementation of construction measures without contact – with the help of thermal images
- Test air-tightness of windows and doors
- Locate insulation errors and cold bridges in a building shell
- Detect and visualize mould-risk areas

Easy checking of heating systems and installations
- Test heating and air conditioning/ventilation systems: Use a thermal imager to identify irregularities in the temperature distribution quickly and easily
- Localization of the course of heating loops in underfloor heating systems
- Testo radiators for silting
- Measure flow and return temperatures

Localize pipe ruptures
- Reliably determine pipe ruptures with the help of a thermal imager – without unnecessarily opening walls and floors
- Precise localization of leakages in underfloor heating and other inaccessible pipe systems

Locating leaks in flat roofs
- Detection of damp in roofs: Based on temperature differences (such as occur mainly in flat roofs), thermal imagers show areas on the roof with sealed-in moisture or damaged insulation
