Fluke FLK-050-CLKT 2″ C-Range IR Window
Reliable IR access becomes much safer when inspections no longer require opening energised panels. This window uses a sealed CLIRVU crystal that holds steady under heat, pressure and shock, giving a clear view for IR and visual checks while keeping equipment closed. Moisture resistance and long-term stability ensure consistent clarity during routine work, even when vibration and humidity rise.
Safety and Clarity
Strong materials allow the optic to withstand extreme temperatures and arc-fault pressure. The crystal tolerates heat up to 1400°C, while the silicone gasket maintains its seal under demanding conditions. Two sentences work together to keep the system protected during inspections, and they support onsite safety rules by reducing exposure to live systems.
Installation and Use
Smooth handling comes from the Kwik Twist cover, which lifts away cleanly and attaches magnetically during work. This shortens inspection time and keeps technicians focused on the task. Two sentences combine to support UV, shortwave, midwave and longwave IR, along with visual and fusion modes, so faults can be identified quickly.
Long-term durability stays central to the design, supported by resistance to chemicals, moisture and vibration. Each unit includes an identification plate for site tracking, a security key and a drilling template for accurate fitting. Two sentences together help ensure the window performs well in demanding settings where safe, repeatable inspections matter.
