    Technical highlights of the testo 865s thermal imager

    The testo 865s thermal imager stands out thanks to its easy operation and has the following impressive technical features:
     
    • Very good image quality due to high resolution: 19,200 temperature measuring points ensure precise thermography. Infrared resolution of 160 x 120 pixels – via integrated SuperResolution Technology 320 x 240 pixels
    • Visualize temperature differences from 0.18 ºF (0.1 ºC)
    • Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
    • The IFOV warner means the distance from the measurement object / measurement spot size is determined and the measurement spot is shown on the thermal image - you therefore avoid measurement errors because the camera shows you exactly what you can measure
    • The testo ScaleAssist automatically ensures optimum setting of the thermal image scale, which means you generate objectively comparable and error-free thermal images, for example of the thermal insulation behavior of buildings
    • Pro software for image evaluation on the PC
    • You can choose to save thermal images as JPEGs

    Overview of applications

    Preventive maintenance

    Detecting structural defects and ensuring construction quality

    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

      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
