The following images were taken as a comparison between the Therm-App smart phone camera (for androids) and the Testo 870-2.
It might seem a strange comparison (as the specifications are vastly different) however the price points are close. The Testo 870-2 is also a dedicated camera platform, whereas the Therm-App is a smart phone attachment.
The following images were taken under extremely cool conditions in Melbourne. This will push both cameras’ sensitivity capabilities to the limits. Day time temp did not exceed 10°C and the environment is varied by little more than 2°C.
