Optimal for quick spot checks
The new testo 860i wireless thermal imaging camera for smartphones with easy operation and display via the testo Smart app. In seconds, you get exactly the information you need for quick spot checks in HVAC/R, maintenance, building technology and many other applications.
Small camera. Great benefits for entrepreneurs and technicians.
Thermography with testo 860i saves time. You can work more flexibly and efficiently.

Advantages of testo 860i
- Easy & fast measurement of Delta T directly in the thermal image with application specific measurement programs.
- Razor-sharp thermal images thanks to high IR resolution (256 x 192 pixels).
- Easy to use & hassle-free documentation with the testo Smart app.
- Flexible thanks to wireless function and mobile phone/tablet mount.
- Highly suitable for daily use and robust construction with IP54 protection class, it can withstand falls up to 1.5 m and has USB-C connectivity.
Everything is easy in the testo Smart app
With the free testo Smart app, you can easily use the testo 860i thermal imager. It connects quickly to your mobile phone or tablet.
The thermal images are displayed clearly in the app and can be easily edited in the thermography measurement program. You also get access to measurement programs for specific applications:
DeltaHeat for quickly determining the spread between flow and return temperatures on radiators.
DeltaCool for quickly determining the differential temperature on air conditioning/cooling systems with step-by-step instructions.
Humidity function for assessing the risk of moisture damage in buildings using the traffic light principle.
Documentation can also be handled conveniently and easily via the app. You can share and quickly create and send PDF reports.
testo 860i is versatile!
Heating systems can be tested very quickly with the testo 860i. The DeltaHeat measurement program helps you determine the spread between flow and return temperatures on radiators.
In the event of deviations, you get information about possible causes and a suggested course of action based on Delta T.
Go to testo 860i >You can check refrigeration and air conditioning systems quickly and easily with the testo 860i. The DeltaCool measurement program helps you determine the temperature difference with step-by-step instructions.
Go to testo 860i >Moisture in walls, for example, can be visualized very clearly in the thermal images. Using the traffic light principle, the camera's humidity function shows where there are thermal weak points and a risk of mold.
You can manually enter the desired temperature and humidity values for rooms or transfer them automatically to the testo Smart app, for example with the testo 605i humidity and temperature probe (optional).
Go to testo 860i > Go to testo 605i >Hidden defects such as water leaks can be detected quickly with the testo 860i without having to damage walls, floors or ceilings.
Go to testo 860i >With the testo 860i, you can quickly and easily identify hotspots on individual components and entire electrical systems.
Alternatively, you can connect the testo 770-3 clamp meter to the testo Smart app. When inspecting a distribution board, for example, you can then record the load status together with the thermal image and reliably assess the condition of the system.
Go to testo 860i > Go to testo 770-3 >The testo 860i is also perfect for preventive maintenance of components and mechanical systems. The camera quickly detects heat build-up in motors, shafts and so on.
