    The testo 871s Thermal Imaging Camera is designed for professionals who need high-resolution thermal imaging, smart connectivity, and precision measurement integration. With an infrared resolution of 240 x 180 pixels (boosted to 480 x 360 pixels with SuperResolution technology), this camera captures sharp, detailed thermal images, making it ideal for HVAC, electrical, and building inspections.

    Equipped with a wide temperature measurement range (-30°C to 650°C) and 80mK thermal sensitivity, the testo 871s detects even the smallest temperature differences, allowing for accurate diagnosis of insulation defects, electrical faults, and mechanical issues. The wide 35˚ x 26˚ field of view ensures fast and efficient inspections over large areas.

    The testo 871s is Wi-Fi enabled, allowing for seamless data transfer and real-time report generation via the testo Thermography App (available for iOS and Android). The app provides: Live second display on a smartphone or tablet, Remote camera operation and On-site report creation and sharing. 

    Additionally, the testo 871s connects via Bluetooth to the testo 770-3 Clamp Meter and testo 605i Thermohygrometer. The testo 770-3 allows you to capture electrical current and voltage data for comprehensive system analysis. the testo 605i allows you to record ambient temperature and humidity conditions for advanced building diagnostics and automatically detect mould risk using the humidity traffic light function.

    The testo ScaleAssist and testo É›-Assist features optimise colour scale settings and emissivity adjustments, ensuring consistent, error-free, and objective thermal images. Automatic hot/cold spot detection instantly identifies critical temperature variations. The IFOV warning system prevents measurement errors by displaying the correct measurement spot size in real-time.

    A built-in digital camera allows users to capture both thermal and visual images simultaneously, making analysis and reporting easier. Images and videos can be saved to the 2.8GB internal memory and transferred via USB or WLAN for further processing.

      • Overview of applications

      Preventive maintenance

      Detecting structural defects and ensuring construction quality

      Preventing mould formation

      Easy checking of heating systems and installations

      Localize pipe ruptures

      Locating leaks in flat roofs

      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

        Preventing mould formation

        • Localize mould-risk areas quickly and easily: These areas are presented in red in the imager display when the imager is in humidity mode

        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

        • 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
