UL Recognized and UL Listed



IR Windows are UL Recognized instead of UL Listed because IR Windows serve no real purpose by themselves. They need to be installed into an electrical enclosure, or onto something, to be used for their
intended purpose.


All Fluke IR Windows are tested to meet the UL50V Infrared Viewport Standard. This standard outlines the necessary testing criteria to achieve UL Recognition.
