The FLIR CM174 has the power to lead you to problems you can't see with a standard clamp meter. Featuring Infrared Guided Measurement (IGM) technology powered by an integrated FLIR Lepton® thermal imaging sensor, the CM174 provides a reliable way to identify hot spots and overloaded circuits from a safe distance. IGM visually guides you to the precise location of a potential problem and helps confirm your findings with a wide range of functions plus temperature readings.
