Need to see what's going on inside your electrical panels but worried about safety? With Fluke's CV300 and CV301 IR windows you can look inside using your thermal camera and easily spot problems while you stay safe with the cabinet closed!

Designed for easy installation and sealed across the entire body for superior protection against arc flash (and the effects of moisture damage - particularly useful in outdoor applications), Fluke's IR windows are extensively tested to the highest standards to ensure that they maintain the safety of those using them at all times.

If you require a smaller or larger IR window, Fluke's CV200 and CV400 windows are also available for purchase.
