DatasheetThe testo 868s thermal imager– smart and networked
The testo 868s thermal imager guarantees wireless communication with your mobile terminal device via WLAN. With the testo Thermography App for iOS and Android you can write and send reports directly on site, as well as saving them online, and you can use your smartphone or tablet as a second display or for remote control.
Areas of application of the testo 868s thermal imager
Detect leaks, identify overheated connections, pinpoint thermal bridges or detect structural defects. The testo 868s thermal imager was developed for applications in daily maintenance and installation work in trade and industry. It enables quick and reliable work when you are detecting defects and carrying out maintenance.
Technical highlights of the testo 868s thermal imager
Really simple operation with impressive thermal imaging technology: the testo 868s thermal imager has the following impressive features:
- Very good image quality due to high resolution: 19,200 temperature measuring points for precise thermography. Infrared resolution of 160 x 120 pixels – extended to 320 x 240 pixels via integrated SuperResolution Technology
- Visualizing temperature differences of 0.08 °C
- The testo Thermography App enables you to write reports on site, save them online and send them by e-mail, as well as allowing you to use mobile terminal devices as a second display or for remote control
- Built-in digital camera generates a real image in parallel to the thermal image
- Automatic hot-cold spot recognition directly displays critical temperature conditions
- The testo ScaleAssist automatically ensures optimum setting of the thermal image scale, which means you generate objectively comparable and error-free thermal images, for example of the thermal insulation behaviour of buildings
- 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

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
