Product Description

The new testo 860i wireless thermal imager for smartphones is easy to use and display in the testo Smart App making it the perfect choice for quick spot checks in HVAC, maintenance, buildings and many other applications.

testo 860i enables quick and easy determination of Delta T (differential temperature) in the thermal image using application-specific measurement functions:
DeltaHeat for quick determination of the spread between the flow and return temperatures of radiators, DeltaCool for quick assessment of the temperature differential in refrigeration and air conditioning systems. The humidity mode function also helps to assess the risk of mould in indoor environments. The thermography measurement function shows hotspots and Delta T quickly and easily during maintenance.

The testo Smart App is used to operate the testo 860i, display the thermal image and differential temperature, and for documentation – it’s simple, fast and smart. The testo 860i can be used flexibly, either directly attached to the smartphone/tablet for one-handed operation or separately. What’s more, its high suitability for everyday use, robustness and rechargeable lithium battery with a long operating time make the testo 860i a reliable companion.
