Product Description

We have created a thermal imager with the testo 868 that expedites and simplifies work without sacrificing expert thermal imaging expertise. With its practical features, you may produce infrared photographs that are fault-free and objectively comparable. With the use of the IFOV Warner, Testo -Assist, and Testo ScaleAssist, you can quickly configure emissivity () and reflected temperature (RTC) for building thermography to their ideal values as well as colour scale.

The testo 868 thermal imager– smart and networked

Wireless communication via WLAN is ensured by the testo 868 thermal imager with your mobile terminal device. With the testo Thermography App for iOS and Android, you can use your smartphone or tablet as a second display, a remote control, and to compose, share, and save reports online while still on the spot.

Areas of application of the testo 868 thermal imager

Find thermal bridges, locate overheated connections, find leaks, or locate structural flaws. The testo 868 thermal imager was created for use in routine installation and maintenance tasks in business and industry. When you are performing maintenance and identifying flaws, it permits rapid and reliable work.

Technical highlights of the testo 868 thermal imager

The testo 868 thermal imager has the following outstanding features despite having a very straightforward operation:

High resolution and 19,200 temperature measuring points for precision thermography result in very good image quality. 160 x 120 pixel infrared resolution with integrated SuperResolution Technology extending that to 320 x 240 pixel infrared resolution
displaying 0.08 °C in temperature differences
You can make reports using the testo Thermography App, save them online, and email them to others. You can also utilise mobile terminal devices as a second display or for remote control.
Parallel to the thermal image, the built-in digital camera produces an actual image.

Critical temperature conditions are instantly displayed via automatic hot-cold spot identification.
In order to produce objectively comparable and error-free thermal images, such as those showing how buildings behave in terms of thermal insulation, the testo ScaleAssist automatically ensures that the thermal image scale is set to the best possible level.
You eliminate measurement errors since the camera shows you exactly what you can measure thanks to the IFOV Warner, which means the distance from the measurement item / measurement spot size is calculated and the measurement spot is shown on the thermal image.
professional computer programmes for evaluating images
JPEGs are an option for saving thermal photos.

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
