testo 868, Thermal imager

The testo 868 thermal imager is specially designed to help you work faster and easier, utilizing all the advantages of the latest professional thermography technologies.

Its convenient functions allow you to obtain error-free and objectively comparable thermograms. The IFOV warner, testo ϵ-Assist, and testo ScaleAssist functions help avoid measurement errors and effortlessly set the optimal values for emissivity (ϵ) and reflected temperature (RTC) for building thermography, as well as the optimal color scale.

The testo 868 Thermal Imager – Smart Thermography for Everyday Tasks

The testo 868 thermal imager connects to your mobile device wirelessly. The testo Thermography App for iOS and Android allows you to compile and forward reports with measurement results directly on site, save them, and also use your smartphone or tablet as a second display or a remote control for the thermal imager.

Application Areas of the testo 868 Thermal Imager
Locating leaks, identifying overheating connections, accurately detecting thermal bridges, or defects in building envelopes.

Description

The testo 868 thermal imager was developed for use in daily maintenance and installation work in construction and industry. It ensures fast and reliable defect detection and technical maintenance.

Key Technical Specifications of the testo 868 Thermal Imager
A combination of unique ease of use with professional measuring technology: the testo 868 thermal imager boasts the following impressive technical characteristics:

  • Very good image quality thanks to high resolution: 19,200 temperature measurement points provide highly accurate thermograms. The detector size is 160 x 120 pixels, and the integrated SuperResolution technology increases the resolution to 320 x 240 pixels
  • Visualization of temperature difference from 0.10 °C
  • The testo Thermography App allows you to write reports right at the measuring site, save them on your mobile device, and send them via e-mail, as well as use your mobile device as a second display or a remote control for the thermal imager
  • The integrated digital camera captures a real image in addition to the thermogram
  • Automatic hot and cold spot recognition allows you to see the critical thermal status directly on the display
  • The testo ScaleAssist function automatically sets optimal temperature scale settings, which allows you to obtain error-free thermograms that are suitable for objective comparison, for example, when checking building airtightness
  • The testo ϵ-Assist function ensures accurate measurement results by automatically determining and setting the values for emissivity and reflected temperature
  • The IFOV warner function determines the distance to the measured object and the size of the smallest measurement spot that is shown on the thermogram. This allows you to avoid measurement errors, as the display shows you exactly what you can measure
  • Professional software for image analysis on a PC
  • You can save thermograms in JPEG format
