Testo 860i Wireless Thermal Imaging for Smartphones

HVAC technicians and salespeople looking to add a serious “wow” tool into your kit without breaking the bank, the Testo 860i is a smart choice.

This compact, smartphone-attached thermal imager turns your mobile device into a thermal camera in seconds. There are no large bulky rigs — just clip and connect, then open the free Testo app and you’re hunting down hot spots in homes.

The 860i has an impressive 256 x 192-pixel infrared sensor that provides great resolution, and you get top capabilities like the ability to measure differential temperature, thermal imaging, and more. It’s rugged enough for the trades. Dropping it won’t hurt it.

It is also small, lightweight, and easy to carry. I find it ideal for one-handed use. The carrying case makes it even more practical for field work. It even has a documentation feature so you can share your findings with customers.

The 860i is affordable: many thermal cameras cost thousands but the 860i is only a few hundred dollars. It is an inexpensive powerhouse for the seasoned tech or the first-year rookie. I believe it provides serious capability for building, electrical, and duct assessments.

If you’re inspecting the building, assessing the HVAC system, or performing a sales demo showing the hidden thermal issues, this instrument seals the deal and provides an “ah-ha!” moment for you and your customers.
