The new testo 860i wireless thermal imager for smart devices gives users simple operation and display paired with the testo Smart App, making it the perfect choice for quick spot checks in the HVAC/R trade, maintenance, buildings, and many other applications.
Testo 860i enables quick and easy measurements of Delta T (differential temperature) in the thermal image using application-specific measurement functions: DeltaHeat for quick readings of supply and return temperatures on heating-type appliances, DeltaCool for quickly establishing the differential temperature in refrigeration and air conditioning systems.
The testo Smart App is used to operate the testo 860i, display the thermal image and differential temperature, and document findings—it’s simple, quick, and smart. The testo 860i is versatile and can be directly attached to a smartphone or tablet or used one-handed separately. Designed for everyday field use, with durability, portability, and a rechargeable lithium battery with a 2-hour operating time, the testo 860i is a reliable companion that can see what we cannot see.
