Five minutes is all it takes to install a Fluke ClirVu® CV Series IR Window, the only IR Window with AutoGround™. With its AutoGround design, Fluke has eliminated the need to separately ground each metal component of the window. The time saved and safety benefits from installation alone clearly make Fluke the preferred choice. 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.
