Testo 868s Thermal Imaging Camera

The Testo 868s Thermal Imaging Camera has several useful features which help the user make the most of its impressive thermographic capabilities. The non-contact infrared thermal sensor has a resolution of 160 x 120 pixels and measures temperature from -30˚C to 650˚C over two separate ranges. Thermal sensitivity is just 80mK meaning that temperature differences as small as 0.1˚C can be visualised on screen. The fixed-focus 31˚ x 23˚ field of view allows the user to make quick inspections over a large area.

Images and video are shown on the Testo 868s' colour screen which has a range of four palettes. The ScaleAssist function automatically selects a colour scale in order to properly highlight temperature differences across the image. Hot and cold spot recognition also highlights the extremes present on screen whilst ε-Assist automatically sets emissivity adjustment in order to maintain accuracy. Optional Testo SuperResolution software artificially increases resolution to 320 x 240 pixels for even more precise thermal imaging.

A digital camera is integrated into the Testo 868s so it can save visible images alongside their thermographic counterparts, thus permitting easier analysis of heat maps. Images and video can be saved to the camera’s large (2.8GB) internal memory and then transferred to a PC via a USB cable or to a smart device with the Testo Thermography App (available for free from Google Play and the App Store) via WLAN wireless connectivity.

The Testo 868s is built with practicality in mind and is sturdy enough to withstand the bumps and scrapes of everyday use. It has an IP54 ingress-protection rating and a four-hour battery life so it is suitable for outdoor use. Several accessories are provided as standard including a USB cable, a battery charger, software, ε-markers, a calibration certificate and a case. Testo also provide a 2-year manufacturer’s warranty.

Testo 868s vs 868

The 868s has received a number of important upgrades over its predecessor model, the 868. In the latest ’s’ model, you will find an improved thermal sensitivity (100mK vs 80mK) and better user interface for a superior user experience. In addition to this, the visual camera megapixel count has increased from 3.1MP to 5.0MP, delivering clearer imagery.
