Oil In Water Sensor

Apure oil in water sensor is a non-contact sensor that detects oil in water in real time. It uses the natural fluorescence of oil to detect anything from marine diesel to vegetable oil to jet fuel and alerts you immediately.

Oil detection is an important factor in a very wide range of industries. We offer equipment for monitoring borehole water down to ppb levels. We can also provide equipment for detecting oil slicks in surface water. Applications include airport runoff, boiler condensate and drinking water inlet protection.

Oils and hydrocarbons are often a major component of a variety of products, from fuels to solvents to the many chemicals used in industry during processing. In industrial production, some of these hydrocarbons, oils and solvents can leak into sewers or, worse, directly into the environment. Similarly, domestic and agricultural fuel storage can lead to accidental spills into waterways and aquifers.

In the oil industry, one ton of oil spilled can quickly spread over an oil slick covering an area of approximately 10,000 sq. m. The Apure over-water oil sensor is carefully calibrated to detect oil and minimize false alarms. The average thickness of an oil slick is 0.1 mm, and our sensors can detect some oil as little as 0.001 mm*.

Oil in water analyzers can be useful by giving early warning of problems as they occur.


Sensors pinpoint pollution day or night, on land or water, and at all temperatures.
