Testo 862-1 Pocket Thermal Imaging Camera
The Testo 862-1 Pocket Thermal Imaging Camera is a compact thermal imager designed for HVAC/R work, building inspections, industrial maintenance and facility management. Its 160 x 120 pixel infrared resolution and thermal sensitivity of less than 50 mK at 25 °C help reveal clear temperature patterns during inspection. A 2 MP visual camera and Fusion image mode add visual detail to thermal images, making areas of interest easier to recognise.
Built-in analysis functions help users assess temperature differences quickly in the field. Hot spot and cold spot detection, DeltaHeat, Delta T, five adjustable measurement spots and three regions of interest support practical fault finding and inspection work. The camera also offers automatic reading transfer from the optional testo 605i thermohygrometer and testo 770-3 clamp meter via Bluetooth, allowing humidity or electrical readings to be combined with inspection tasks.
The Testo 862-1 Pocket Thermal Imaging Camera is made for straightforward everyday use, with fixed focus, a 25 Hz image refresh rate and a measurement range from -10 °C to 550 °C. It includes 12 GB of user storage, non-radiometric AVI video recording and several thermal colour palettes. An IP54 housing, 1.5 m impact resistance, rechargeable Li-ion battery and USB-C charging make it practical for regular field use.
