Xi`an Desun Uniwill Electronic Technology Co., Ltd products

Commonly used oil in water detection methods include suspension method (D/λ<=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. 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 DS380 series of fluorescent dissolved oxygen sensorsuse a new generation of fluorescence lifetime technology andhighperformance fluorescent materials. No oxygen consumption,o flow rate limitation, no electrolyte, no maintenance and calibration,no interference from hydrogen sulfide, excellent stability. Built-intemperature sensor, automatic temperature compensation. RS485 output, can be networked without a controller.

Our company applies optical fiber technology to the turbidity sensor, which makes the sensor have better repeatability and stability, and is not easily affected by the ambient light. The automatic cleaning brush with the sensor can effectively eliminate air bubbles and reduce the impact of contamination on the measurement, make the maintenance cycle longer, and maintain excellent stability for long-term online use 485 output, support MODBUS with automatic cleaning brush, prevent contamination, strong anti-interference ability to eliminate bubbles, not affected by ambient light and chromaticity 90 ° scattered light principle, using fiber optic technology has better repeatability.

The fiber-optic chlorophyll sensor adopts the principle of fluorescence method. According to the spectral absorption characteristics of chlorophyll a, it irradiates water with a high-energy LED light source to excite the chlorophyll a in the water to generate a specific wavelength of fluorescence and measure the concentration of chlorophyll a in water. The sensor uses a fiber-optic structure with excellent repeatability and stability, and is not easily affected by ambient light. Equipped with an automatic cleaning brush to eliminate air bubbles and reduce the impact of contamination on the measurement, make the maintenance cycle longer, and maintain excellent stability for long-term online use.
