CRAB - 1

Oil slicks optical detector Remote optical sensing of water surface with vertical laser beam MM Continuous remote optical sensing, no sampling Principle of operation Is based on the difference in light reflection from water and oil film surface Applications MM Monitoring of water surfaces (sea, harbors, lakes, rivers) MM Oil leakage detection MM Monitoring of process and waste waters MM High sensitivity: detection of oil slicks with thickness down to 0.5 micron MM No interference from scattered radiation MM Low interference from ripples and waves (beam/surface angle up to ±20°) MM Built-in data acquisition and processing MM Waterproof housing for outdoor installation MM Ex-proof option is available MM Mounting at stationary points, buoys, motor boats MM Long-term operation without maintenance MM Stationary monitoring and mobile surveys
