The petroleum hydrocarbon sensor is a new generation of high precision sensor based on ultraviolet fluorescence analysis. The sensor is mainly composed of the excitation light source LED, photodiode and signal processing. It can measure light oil, heavy oil and water temperature at the same time. The surface of the sensor optical lens is coated to prevent oil from adhering, and it has a dual-range adaptive function to solve challenge at different concentrations.

Applications：

Suitable for water environment monitoring, drinking water production, raw water treatment, waste liquid discharge, sewage treatment, oil refineries, oil fields and so on. Reagents-free, sensitivity and selectivity, portable use help facing harsh challenge.
