Wall-mounted Nitrite Ion/Nitrite Analyzer
Product Introduction
The online nitrite analyzer is a precision instrument mainly used to detect nitrite ions in liquids. There is a nitrite ion selective membrane at the front end of the sensor. When the sensor is placed in the measured solution, nitrite ions in the solution enter the interior of the sensor through the selective membrane. The cation inside the sensor rises and forms a tiny potential difference with the reference electrode. The magnitude of the potential difference is proportional to the concentration of nitrite ions. The potential difference is amplified and processed through a circuit, so as to obtain the concentration of nitrite ions.
