FLIR (Forward Looking InfraRed) Sensors are unique because they use heat instead of light to capture images. They are incredibly accurate at detecting minute differences in heat and are able to create an incredibly accurate visual when certain situations call for it.
There are few arguments against the fact that FLIR is the ideal technology to utilize for preventative maintenance. On industrial sites, nearly everything gets hot before it fails. Failures can cause fiscal losses, ruin rapport, and even threaten lives.
