Product Description
Our Reagent - free Online Ammonia Nitrogen Sensor is a game -
changer in urban sewage treatment. Without the need for reagents,
it's not only environmentally friendly but also cost - effective.
This sensor can continuously and accurately monitor the ammonia
nitrogen content in influent, during treatment processes, and in
the final effluent of urban sewage treatment plants. The real -
time data it provides enables workers to promptly adjust treatment
parameters. By doing so, it ensures that the treated sewage meets
the discharge standards, effectively preventing water
eutrophication. With its advanced technology, it offers reliable
and stable performance, making it an essential tool for urban
sewage treatment and environmental protection.
Feature
- Digital sensor, RS-485 output, supports MODBUS;
- Ion electrode method, no electrolyte required, electrodes can be
replaced separately, easy to maintain.
- No reagents required, no pollution, more economical and
environmentally friendly;
- Automatically compensate for pH and temperature in water;
