Online Optical Dissolved Oxygen Sensor FDO 700IQ

Using green LED! Extending the lifespan of the sensor cap.

Using a green LED as the light source. Compared to the blue light of conventional optical DO sensors, the consumption rate of fluorescent materials is reduced, achieving a longer lifespan for the sensor cap. 【Features】 ■ Adopts high-precision, long-life soft green light emission technology ■ Avoids drift through EPRS method ■ Low maintenance ■ Easy installation ■ High-precision measurement possible from the moment of installation ■ Records factory calibration data and maintenance data with a data chip embedded in the sensor cap, which can be automatically retrieved simply by connecting to the IQ sensor network system ■ 2-year warranty *For other functions and details, please download the catalog.
