Model OCM-15 15ppm bilge water alarm instrument is not only used for the continuous detection of oil and sewage in the bilge of ship, but also used for the monitoring of oily waste water in the fields of chemical industry, petroleum and environmental protection etc.
Model OCM-15 15ppm bilge water alarm instrument and its technical performance conforms to the third part “ Authorization of Technical Conditions of Environmental test of Antipollution Equipments”, the second section “ Authorized Test and Performance Technical Conditions of 15ppm Warning Device for Bilge Water”, MEPC.107(49) Resolution - “Revised Guide and Technical Conditions of Anti-pollution Equipments for Bilge Water in Ship Craft” which was passed on the 18th, July of 2003. This instrument has the advantages of compacting and firm design structure, IP45 guard rank, so it can completely adapts to the working environment in cabin. 15ppm bilge water alarm instrument has a lot of functions, such as, to display measurement result, set 15ppm warning value, output analog signal of sewage standard discharge control total amount to measurement value, and also provide these services including data print, storing and inquiry of historical data etc. Besides,15ppm bilge water alarm instrument can record date, time, alarming state and running state.
