A company's greatest investment is not the equipment that's behind the panel door; top priority is to offer the ultimate protection for the electricians, engineers and inspectors who risk their lives every day doing their jobs. The ClirVu® coating - exclusive to Fluke infrared windows - seals the optic prior to assembly to protect against moisture degradation making it perfect for very hot and very cold environments. Each Fluke infrared window is delivered with an identification plate attached for unique, on-site numbering for rapid location confirmation and faster repairs.  For a security key access option see the CV401 IR Window.  The CV Series of infrared windows are also available in 50 mm (2 in) and 75 mm (3 in) sizes.
