Wall-mounted Nitrate Nitrogen Analyzer
Product Introduction
The online nitrate nitrogen analyzer is a precision instrument mainly used to detect nitrate nitrogen ions in liquids. There is a nitrate nitrogen ion selective membrane at the front end of the sensor. When the sensor is placed in the measured solution, nitrate nitrogen ions in the solution enter the inside of the sensor through the selective membrane. The cation concentration inside the sensor increases, forming a tiny potential difference with the reference electrode. The potential difference is proportional to the concentration of nitrate nitrogen ions. The potential difference is amplified by the circuit to obtain the concentration of nitrate nitrogen ions.
