The window models IRW-xPC and IRW-xPS allow more efficient inspections, enable access to hard-to-reach components and save costs by avoiding unplanned downtimes. The rectangular polymer windows are impact-resistant and offer a large field of vision for non-invasive monitoring of the components of live electrical systems. The FLIR IR window models xPC and xPS prove to be particularly durable and stable even in harsh environments. Therefore, they are suitable for most industrial applications as well as for use on ships.
