"Online oil-in-water" analyzers measure very low concentrations of dissolved hydrocarbons in water. This is usually of concern as it is the first indication that an oil or fuel spill has occurred.
Commonly used oil-in-water detection methods include the suspension method (D 1), infrared spectrophotometry (not suitable for low range), and ultraviolet spectrophotometry (not suitable for high range). Our online oil-in-water sensor uses the principle of fluorescence. Compared with several commonly used methods, the fluorescence method is more efficient and quicker and can be monitored online in real time. The sensor has better repeatability and stability. The self-cleaning brush can be used to eliminate air bubbles, reduce the impact of contamination on the measurement, make the maintenance cycle longer, and maintain excellent stability for long-term online use. It can play an early warning role on oil pollution in water. Suitable for oil quality monitoring, industrial circulating water, condensate, wastewater treatment, surface water stations, and other water quality monitoring scenarios
The oil content in the water was monitored by the ultraviolet fluorescence method, and the concentration of oil in the water was quantitatively analyzed according to the present intensity of the oil and its aromatic hydrocarbon compound and the conjugated double bond compound absorbing ultraviolet light. The aromatic hydrocarbons in petroleum can generate fluorescence under the excitation of ultraviolet light, and one can calculate the value of oil in water according to the intensity of fluorescence.
FEATURES :
- Digital sensor, RS-485 output, support MODBUS
- With automatic cleaning brush to eliminate the impact of oil on the
- measurement
- Eliminate the effects of ambient light on measurements with unique optical
- and electronic filtering techniques
- Unaffected by suspended solids in water

It is a water quality instrument that continuously measures the concentration of oil or hydrocarbons in water using advanced sensing technology.
The analyzer uses the ultraviolet fluorescence method to detect oil particles, which provides efficient and real-time monitoring of even low concentrations.
It’s commonly used in applications like industrial wastewater monitoring, circulating water systems, surface water stations, condensate control, and environmental compliance monitoring.
It features RS-485 digital output with Modbus support, automatic optical filtering to reduce ambient light interference, and a design that is unaffected by suspended solids in water.
The analyzer is available in ranges such as 0-50 ppm (or 0-5000 ppb) with a resolution of 0.1 ppm/0.1 ppb and precision around 3 %, suitable for precise oil detection.
