- Superior Image Quality: The testo 865 provides high resolution with 19,200 temperature measuring points to ensure precise thermography. It features an infrared resolution of 160 x 120 pixels, which can be enhanced to 320 x 240 pixels via integrated SuperResolution Technology.
- High-Sensitivity Performance: As a high-sensitivity thermal camera, it allows you to visualize temperature differences from as low as 0.1°C, making it easy to identify even minor thermal anomalies.
- Automatic Spot Recognition: Critical temperature conditions are directly displayed on this infrared camera via automatic hot-cold spot recognition.
- IFOV Warner: The integrated IFOV warner helps you determine the correct distance from the measurement object. By showing the exact measurement spot on the testo 865 thermal imager, it ensures you avoid measurement errors and capture only what is intended.
- testo ScaleAssist: This portable thermal imager includes testo ScaleAssist, which automatically ensures the optimum setting of the thermal image scale. This allows you to generate objectively comparable and error-free thermal images, ideal for analyzing the insulation behavior of buildings.
- Professional Evaluation: Includes Pro software for comprehensive image evaluation and data analysis on the PC.
- Flexible Documentation: You can choose to save thermal images captured by the testo 865 as JPEGs for easy sharing and reporting.

Frequently Asked Questions
Yes, the testo 865 thermal imager is specifically optimized for contractors and service technicians. Its robust design and "switch on and go" interface make it a reliable portable thermal imager for checking electrical cabinets, HVAC systems, and building insulation.
SuperResolution is a patented technology from Testo that uses the natural movement of your hand to capture multiple images and combine them. This effectively doubles the resolution of the testo 865 from 160 x 120 to 320 x 240 pixels, providing much sharper thermographic detail.
Thermal sensitivity (NETD) refers to the smallest temperature difference the camera can detect. With a sensitivity of 100 mK (0.1°C), the testo 865 is a high-sensitivity thermal camera capable of identifying subtle heat leaks or moisture patches that lower-spec devices might miss.
Absolutely. Thanks to its precision and automatic hot/cold spot recognition, it is an excellent infrared camera for locating the exact path of heating loops or pinpointing leaks in underfloor systems without having to open up the floor.
Yes, every testo 865 thermal imager comes with the IRSoft professional software. This allows you to transfer your thermal images to a PC, conduct deep analysis, and generate professional reports for your clients in a matter of minutes.
