testo 862-1 Pocket Thermal Imager with 160 x 120 IR Resolution
Professional Thermal Imaging Made Fast, Simple, and Portable
The testo 862-1 Thermal Imager delivers thermal insights instantly in a compact, pocket-sized design built for HVAC/R, industrial maintenance, facility management, and building diagnostics. Whether performing routine inspections, troubleshooting equipment, or identifying hidden issues, the testo 862-1 helps professionals work faster and with greater confidence. Equipped with a 160 x 120 infrared detector and thermal sensitivity of less than 50 mK, the testo 862-1 captures clear thermal images that reveal temperature anomalies quickly. Fusion technology overlays thermal and visual images to provide added context, making findings easier to interpret, document, and communicate.
Built-in diagnostic tools such as hot and cold spot detection, automatic Delta T calculations, alarm functions, intelligent mold analysis, and DeltaHeat radiator diagnostics help streamline inspections and support faster decision-making in the field. Wireless connectivity with compatible testo instruments, including the testo 605i Thermohygrometer and testo 770-3 Clamp Meter, further enhances reporting and measurement workflows by integrating additional system data directly into inspections. Designed for demanding jobsite conditions, the testo 862-1 features an IP54-rated housing and drop protection up to 1.5 meters, providing reliable performance for everyday professional use.
