The air/water cooled housing allows the sensor to withstand ambient temperatures which exceed the normal 70°C limit. Air or water, depending on the level of cooling required, flows into one of the fittings on the side and out of the other. To prevent condensation forming on the lens, the housing is also supplied with an air purge collar.
Note: the air/water cooled housing must be ordered with the sensor as it cannot be retro-fitted.
