The ThermoClipTM Series serve as overtemperature indicators for electrical assets. Using a patented thermochromic technology, these easily-installed clips provide a color-changing visual indicator that work in tandem with the large format windows from IRISS as part of the visual component in the inspection process prior to and between infrared and ultrasound inspections. With a memory-effect feature, these non-conducive clips can also let inspectors see a permanent record of overtemperature excursions in intermittently loaded systems.
