Note: There are two versions of this product available (use the dropdown box to make a selection). The only difference between the two is that model CV401 comes with a security key whereas CV400 does not.

The largest of Fluke's CV infrared windows, the CV400 and CV401 directly install on electrical panels and allow users to see what's happening inside.

They are universally compatible with all Fluke thermal imaging cameras, suitable for use both indoors and outdoors and offer superior protection against electrical shock and the effects of arc flash. Fluke's IR windows are also incredibly easy to install, seal firmly in place and automatically ground themselves to ensure the protection of users at all times.

Each window comes with a uniquely marked identification plate, allowing unique, on-site numbering for rapid location confirmation and faster repairs.
