Key features

Fluke CLKT Infrared Windows are Available in Three Sizes 50 mm (2 in), 75 mm (3 in) and 100 mm (4 in)

Each CLKT infrared window is engineered and tested to withstand electric-arcs up to 50 kA for 30 cycles.

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 outdoor environments.

Each Fluke infrared window is delivered with an identification plate attached for unique, on-site numbering for rapid location confirmation and faster repairs.

Save Time and Conduct More Efficient Electrical Infrared Inspections

Once you've installed a Fluke infrared window there is no more need to power down or remove panel doors – you may never have to open the panel door again. Inspections are now conducted quickly, easily and safer than they were before.

Your greatest investment is not what's behind the panel door; your priority is to offer the ultimate protection for the electricians, engineers and inspectors who risk their lives every day doing their jobs.

Rated 4 out of 5 by from Standard equipment for new PDC's We have made this standard equipment for new construction PDC's, designing IR inspection in from the time of order. We've added the Fluke 100 CLKT IR to our PDC spec with both Siemens and Eaton. They have been able to include these windows while maintaining the ANSI C37.20.7 arc resistant rating of the PDC (although I may consider changing the IR window spec to the CV401, which has a higher rating 63kA vs 50kA for 30 cycles). We have also retrofitted some existing PDC's to utilize these windows. In every case, the goal is the same: to enhance our electrical maintenance program through IR inspections, while reducing the hazard (our PDC's are typically in excess of 40 cal/cm^2 for the main breaker... an Extreme Danger that would otherwise restrict our inspections). We did receive a drilling template (I see other reviews asking about this) from Fluke customer service ("4 INCH_3794422_DRILLING TEMPLATE CUSTOMER COPY.pdf"). It would be very useful if Fluke would add this to the Resources tab for these products, but they are available on request. We do find we need to use the security key to remove the cover during IR inspection. I've seen these identified as "hand turn" (in the product comparison table) and the "Models" tab identifies a feature as "Kwik Twist". It looks like you should be able to press and turn to remove the cover, but we haven't found that to be as friendly as we'd like. This requires a bit of strategy to make sure the security key is readily available during inspections. I think a thumb screw might be a better design choice (especially if you could pivot the cover out of the way and hand tighten it down to hold it their during the IR inspection). Overall, these devices are an important part of our electrical PM process while complying with arc flash hazards.

Rated 4 out of 5 by from Drill holes to mount the Ir wondow Salutes. I had bought a IR window to installed in a Door, the issue that I have now it's I don't have physically the IR window, because of that I can't make the drill holes, I would like to view some Pdf where the dimensions of the drill holes and how they are distributed where shown, This way I can take an advantage to my work by the time the IR windows arrives to my hands.
