China Wholesale COD&Ammonia&TN&TP etc Suppliers Factories - IoT Digital Nitrate Nitrogen Sensor – BOQU Detail:
Measuring Principle
NO3-N will be absorbed at 210 nm UV light. When the Spectrometer Nitrate sensor is working, the water sample flows through the slit. When the light from the light source in the sensor passes through the slit, part of the light is absorbed by the sample flowing in the slit, and the other light passes through the sample and reaches the other side of the sensor. Calculate the concentration of nitrate.
Main Features
1) Nitrate nitrogen sensor is directly measurement without sampling and pre-processing.
2) No chemical reagents, no secondary pollution.
3) Short response time and continuous online measurement.
4) The sensor has an automatic cleaning function that reduces maintenance.
5) Sensor power supply positive and negative reverse connection protection.
6) Sensor RS485 A/B terminal is connected to the power supply protection
Application
1) Drinking water / surface water
2) Industrial production process water / sewage treatment, etc.,
3) Continuously monitor the concentration of nitrate dissolved in water, especially for monitoring sewage aeration tanks, controlling denitrification process
