Fluke CV400 ClirVu 95mm Infrared Window

The Fluke CV400 ClirVu 95 mm Infrared Window gives engineers and technicians a fast and safe way to inspect energised equipment. It allows clear infrared and visual inspections without opening panels, helping to prevent arc-flash exposure. Built for efficiency, the Fluke CV400 installs in under five minutes with a single technician and a standard punch tool. It provides strong grounding through its AutoGround feature, maintaining arc ratings up to 63 kA when correctly fitted.

Built for Harsh Environments

Fluke CV400 performs reliably in extreme conditions, from -40°C to +232°C, and up to +260°C for intermittent operation. Its ClirVu coating seals the optic before assembly to prevent moisture damage, ensuring clear imaging even in high-humidity or dusty settings. The rugged construction meets IP67, NEMA 4/12, and marine standards, allowing use in offshore and industrial environments where safety is vital.

Reliable and Efficient Operation

With its permanently attached cover and jam-nut locking system, the Fluke CV400 enhances workplace safety while reducing maintenance time. It eliminates the need to remove panel doors and reduces PPE requirements under NFPA 70E guidelines. Compatible with all Fluke infrared cameras, it supports short, mid, and long-wave IR and UV inspection, ensuring accurate results in every use.

Every Fluke CV400 unit undergoes rigorous testing, including IEEE C37.20.7 arc-blast trials, vibration and humidity verification, and full component certification. Designed for longevity, it comes with a lifetime replacement warranty against manufacturing defects, giving professionals confidence during every inspection.
