What is the FLIR IRW-3S Infrared Inspection Window?
The FLIR IRW-3S 3” Stainless Steel IR Inspection Window is designed for UK electricians and electrical maintenance technicians who carry out thermal imaging inspections on live electrical cabinets. It allows safe visual and infrared inspection without opening panels, helping reduce arc-flash risk while improving inspection efficiency.
Built with a stainless steel AISI 316 housing and a crystal IR (calcium fluoride) optic, the IRW-3S provides clear thermal and visible light transmission for accurate fault detection using FLIR thermal cameras. It’s ideal for routine condition monitoring, preventative maintenance and compliance checks in industrial and commercial environments.
How does the IRW-3S improve electrical inspections?
By allowing inspections through a sealed window, the IRW-3S helps electricians identify overheating connections and load issues without removing panel covers. The result is faster inspections, reduced downtime and safer working practices, especially in high-risk or high-traffic electrical installations.
