Aumeascon AM-D-NO3N Digital Nitrate Nitrogen Sensor

AM-D-NO3N  Digital Nitrate Nitrogen Sensor



Brief Introduction

The Aumeascon AM-D-NO3N is digital online nitrate nitrogen sensor and with RS485 Modbus,it measure the nitrate nitrogen concentration by an ion selective electrode method. The nitrate ion selective electrode directly detects the nitrate ion in the water environment to determine the concentration of nitrate nitrogen. Use a pH electrode as a reference electrode for better stability. The concentration of nitrate nitrogen in the measurement process is easily interfered by potassium ions, so potassium ion compensation is required.

The digital nitrate nitrogen sensor is an integrated sensor that is composed of nitrate ion selective electrode, potassium ion (optional), pH electrode and temperature electrode. These parameters can mutually correct and compensate the measured value of nitrate nitrogen, and meanwhile achieve the measurement for multiple parameters.

Technical Features

1) Nitrate nitrogen measured directly without reagent cost.

2) Optional potassium(K+) measurement compensates for cross sensitivities and ensures reliable measuring results.

3) Digital RS485 sensor, strong anti-interference ability, long transmission distance.

4) Reverse polarity protection of Nitrate nitrogen sensor power.

 

Application

It is widely used to measure the value of nitrate nitrogen in the nitrification treatment and aeration tanks of the sewage treatment plants, industrial engineering as well as river water.
