Series 3000 MkII


Series 3000 MkII offers excellent reliability and ease of use with smart gas sensors which configure automatically when plugged into the transmitter. Onboard diagnostics provide a wealth of useful information during operation and fault finding routines. In addition, the patented ‘Reflex’ sensors test algorithms to ensure sensing elements are fitted and operational at all times. For extra flexibility, the remote sensor can be mounted up to 15m (50 feet) away from the transmitter making the Series 3000 MkII the ideal choice for applications where the point of detection is located in a hard-to-reach area, e.g. in high or low level concealed areas or inside a room with the transmitter located outside.

The gas sensors available for the Series 3000 MkII include Oxygen, Carbon Monoxide, Hydrogen Sulphide, Chlorine, Sulphur Dioxide, Chlorine Dioxide, Nitrogen Monoxide, Nitrogen Dioxide, Hydrogen, Hydrogen Fluoride, Ammonia and Phosphine. Further releases will include Hydrogen Chloride, Hydrogen Cyanide and Ozone. Series 3000 MkII is ATEX, IECEx, UL and c-UL certified.
