The DECKMA OMD (Oil Monitoring Device) is a precision sensor developed by DECKMA Hamburg GmbH, used primarily in marine and industrial settings to monitor oil content in water, especially bilge and ballast discharge. Designed to comply with MARPOL regulations (typically the 15 ppm limit), the OMD detects oil-in-water concentrations using advanced optical technology and provides real-time data to ensure environmental compliance.
