Overview

The WTF203 digital nitrate nitrogen sensor, based on the Lambert Beer absorption law, uses a specific dual wavelength high brightness UV LED to irradiate nitrate ions in water samples. The absorbed light intensity signal is correlated with the nitrate ion content. The sensor adopts a digital and intelligent sensor design concept, which can automatically compensate for the impact of light source fluctuations and device aging on measurement values. Directly outputting standardized digital signals enables networking and system integration without the need for a controller.
