Fluke CV301 ClirVu 75mm Locking Infrared Window

The Fluke CV301 ClirVu 75mm Locking Infrared Window enables safe and fast thermal inspections without opening energised panels. It is designed for use in demanding electrical environments where safety and reliability are critical. Each unit allows clear infrared imaging while protecting personnel from arc-flash hazards and exposure to energised components.

Built for Reliability

The ClirVu coating seals the optic before assembly to prevent moisture damage and maintain clarity over time. This makes the Fluke CV301 ClirVu ideal for very hot and extremely cold settings, maintaining optical quality in tough conditions. The patented AutoGround process ensures the window grounds instantly to the panel enclosure, removing the need for extra grounding steps and reducing installation time.

Performance and Safety

It has been tested to endure arc blasts up to 63kA for 30 cycles at 60 Hz, verified at KEMA laboratories. The IP67 and Type 4 ratings guarantee resistance to dust, moisture and harsh environmental factors. The stainless steel cover and security key latch offer strong protection for both indoor and outdoor applications, while supporting compliance with NFPA 70E and CSA standards.

The Fluke CV301 ClirVu 75mm Locking Infrared Window gives engineers a safer, faster and more efficient way to inspect equipment. It helps lower maintenance time, reduces PPE requirements and ensures accurate temperature readings through its high-transmission optic.
