    Description

    The testo 868s Thermal Imaging Camera is a cutting-edge thermal imaging tool that brings together high-quality thermal diagnostics and modern connectivity. With an IR resolution of 160 x 120 pixels (enhanced to 320 x 240 pixels with SuperResolution), delivering clear and precise thermal images for detecting insulation defects, electrical faults, and leaks.

    With exceptional thermal sensitivity of 0.08°C, the testo 868s can detect even the slightest temperature variations, ensuring accurate and reliable inspections. The automatic hot/cold spot detection feature highlights critical areas instantly, reducing analysis time and improving efficiency.

    A key highlight of the testo 868s is its Wi-Fi connectivity and app integration. The testo Thermography App (iOS & Android) turns your smartphone or tablet into a second display and remote control, allowing you to analyse images, create reports, and send data instantly from the field. This real-time sharing capability streamlines workflows, making it easier than ever to document and communicate findings.

    Additional features like the IFOV warning system, testo ScaleAssist, and testo ɛ-Assist ensure error-free measurements by optimising emissivity settings and colour scales for consistent, reliable thermal images. Thermal images can also be saved as JPEGs, providing compatibility with standard reporting tools.

    Designed for rugged professional use, the testo 868s is built to withstand daily wear and tear. Its IP54-rated dust- and splash-proof housing ensures durability in harsh environments. The rechargeable battery provides up to 4 hours of continuous operation, ensuring uninterrupted inspections.

    Whether you're performing predictive maintenance, electrical inspections, or building diagnostics, the testo 868s delivers best-in-class thermal imaging with smart functionality to make your job easier and more efficient.

        • Applications

          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
