With the testo 868 thermal imager, we have developed a thermal imager which makes work quicker and easier – without foregoing professional thermal imaging technology. You can generate error-free and objectively comparable infrared images using its handy functions. The IFOV warner, testo ɛ-Assist and testo ScaleAssist mean you can avoid measurement errors and not only effortlessly achieve optimum setting of emissivity (ɛ) and reflected temperature (RTC) for building thermography, but also of colour scale.

The testo 868 thermal imager– smart and networked

The testo 868 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 868 thermal imager

Detect leaks, identify overheated connections, pinpoint thermal bridges or detect structural defects. The testo 868 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 868 thermal imager

Really simple operation with impressive thermal imaging technology: the testo 868 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 0.10 °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 testo ɛ-Assist ensures the correct measurement result by automatically determining and setting the emissivity and reflected temperature
  • 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

Detecting structural defects and ensuring construction quality (especially: air tightness of windows and doors)

Analysis with a Testo thermal imager is a fast and efficient method of detecting possible structural defects. Furthermore, Testo thermal imagers are ideally suited for providing proof of the quality and correct implementation of construction measures. Any heat losses, humidity and lack of air tightness in a building are visible in the thermal image. The Testo thermal imager makes it possible to detect faulty thermal insulation and structural damage – all using a non-contact method! The testo ScaleAssist function, which automatically ensures optimum setting of the thermal image scale, means you get objectively comparable thermal images of buildings. This makes correct assessment of structural defects and thermal bridges easier than ever before. Checking the air tightness of windows and doors is one of the typical applications of the thermal imager.

Easy checking of heating and installation systems

Testo thermal imagers are easy and intuitive to operate, so they are ideal for quickly and reliably checking heating, ventilation and air conditioning systems. Just a quick look with the thermal imager is enough to discover irregularities in temperature distribution. Thus, thermography can be used to easily locate clogged radiators and leaks. Typical applications for the thermal imager:
  • Checking radiators for silting
  • Locating leaks
  • Measuring the flow and return temperature
  • Pinpointing the course of heating loops in an underfloor heating system

Support in preventive maintenance

Reliable early detection of damage to production-relevant systems is essential in order to guarantee the safety and reliability of the system and prevent costly downtimes. Problematic areas in electrical and mechanical production facilities usually become evident due to an increase in temperature of the affected components. You can use a thermal imager to detect critical heat conditions (known as hotspots) in your system directly during operation, therefore guaranteeing an additional bonus in terms of reliability. Typical applications for the thermal imager:
  • Quick location of hotspots in electrical installations
  • Detection of critical heat conditions in engines, shafts and bearings
