    FAQ
    ❯

    Oil-in-water sensors utilize the characteristic that soluble oils exhibit absorption and emission peaks in their spectra. When monochromatic light matching the absorption peak of soluble oils is irradiated into water, the soluble oils absorb the monochromatic light energy and release monochromatic light at another wavelength corresponding to their emission peak. The intensity of light emitted by the soluble oils is directly proportional to their concentration in the water.

    ❯

    Oil-in-water sensors detect oil content in water in real time, identifying different forms such as emulsified oil, dispersed oil, and dissolved oil. This enables users to monitor water quality changes and prevent pollution spread. These sensors are widely used in industrial wastewater, oilfield produced water, and ship discharge monitoring to ensure water quality meets environmental discharge standards.

    ❯

    Most oil-in-water sensors feature an IP68 or equivalent protection rating, enabling long-term submerged operation and adaptability to complex environments like sewage or seawater. Their corrosion-resistant structural design ensures stable performance in demanding settings such as mining sites and chemical plants.
