LDI ROW Oil Detector

The LDI's Remote Optical Watcher (ROW) is an autonomous non-contact fluorescence-based instrument for early detection of oil on water in real-time. The ROW series ensure that industrial processes remain safe and risks to the environment are alerted immediately.

ROW DETECTS: motor oils, turbine oils,vegetable oils, fuel oils, marine diesel oils, crude oils, heating oils, lube oils, hydraulic oils, gas oils, motor oils, mineral oils. Available in Aluminum enclosure, intrinsically safe ATEX Exd for hazardous environments, and Stainless Steel for corrosive conditions. The Light Fraction ROW model detects all three major oil fractions: heavy (crude etc...), medium (diesel etc...), and light (kerosene etc...), it is also available in Stainless Steel and ATEX Exd enclosures.
