Application Support

Product Detail

The 30J enclosure has been designed to allow quick and easy access to its interior by adjustment of two allen screws, this factor is a major consideration when large system service and calibrations are being carried out. The detector is robust and weather-proof with improved response times due to the four mounting spacers allowing increased air movement around the detector these spacers also improve the mounting of the unit particularly on circular pillars typically found in carparks. Standard 4~20mA signalling with CANbus address enables the sensors to be networked via the WatchGas Combi control system or customer preferred monitoring system.
