Testo 860i Thermal Imaging Camera
The Testo 860i Thermal Imaging Camera delivers fast, accurate, and reliable thermal measurements for HVAC, electrical, and building inspection tasks. It connects wirelessly to a smartphone or tablet, giving users a clear view of thermal images in real time. With its robust build and advanced features, it is suited for both daily checks and detailed diagnostic work. Professionals can operate it with one hand, whether it is attached to a device or used on its own.
Equipped with high-resolution infrared imaging, the Testo 860i captures sharp and detailed visuals. Its DeltaHeat and DeltaCool functions quickly highlight temperature differences in heating and cooling systems. The humidity mode helps identify mould risk indoors, while thermography mode finds hotspots and other problem areas during maintenance.
Versatile Kits for Specific Needs
Available as part of two specialist kits, the Testo 860i offers greater versatility for different applications. In the Testo Smartprobe Thermal Imaging Mould Kit, it works alongside the 605i Thermohygrometer to detect both temperature and humidity conditions that could cause mould. For electrical and HVAC work, the Testo 860i Electrical Kit pairs the camera with the 770-3 Clamp Meter to combine thermal imaging with accurate electrical measurements. Both kits work seamlessly with the Testo Smart App for recording and sharing results.
Built for Demanding Environments
The Testo 860i features IP54 dust and water resistance and can withstand drops of up to 1.5 metres. Its rechargeable lithium battery provides extended operating time, making it ideal for long field sessions. The lightweight design ensures ease of use even in tight or awkward spaces. The Smart App adds further value, enabling quick reporting and instant sharing via email.
From quick diagnostics to detailed surveys, the Testo 860i Thermal Imaging Camera offers the performance and durability that professionals need. Whether used alone or as part of a kit, it helps ensure accurate results, efficient workflow, and compliance with industry standards.
