These large-size, 95mm windows are perfect for seeing what's going on inside a large section of electrical panels.
To use, simply install (can easily be done in under five minutes) lift up the flap and point your Fluke thermal camera at the window. You can then capture a thermal image of the inside of the panel and ensure your safety because you don't have to open it up.
These windows are suitable for use both indoors and outdoors and boast extreme, superior protection against arc flash, electrical shock, UV rays (such as sunlight) and moisture damage. The window can be locked (model CV401 only) or alternatively can be left open for easy access whenever you need it.
Want to install multiple windows on different systems? Each CV400 or CV401 window comes with a unique code identifier so you can quickly and easily determine which window you need and make documentation/repairs.
