GasEye Extractive Wall Mounted type analyzer exists in general purpose and hazardous area configuration (version Ex1). It exists in several various configurations from single gas to multi gas applications. The system is IP66 rated with ambient temperature ranges from -30 +60 degC and can be mounted outside without a need for a container.
GasEye Extractive Ex1 provides Ex p (purge and pressurization) type of explosion protection. Ex p pressurized equipment is the technique of guarding against ingress of the external atmosphere into an enclosure by maintaining a protective gas therein at a pressure above that of the external atmosphere. The overpressure is maintained either with or without a continuous flow of the protective gas.
