Product Description

Ammonia Nitrogen Sensor for Wastewater Treatment

What's this product?   

      The Ammonia Sensor is a digital sensor featuring an easy-to-integrate RS485 communication interface and standard Modbus protocol, It is equipped with a corrosion-resistant housing, IP68 protection rating, suitable for operation in various harsh working environments;

      Utilize high-stability industrial-grade online ion-selective electrodes, which require no reagents, eliminate secondary contamination, and feature minimal maintenance requirements with low operational costs

      Equipped with a built-in PT1000 temperature sensor and compensation algorithm, achieving an accuracy of ±0.1℃

Operation principle

       The suspended solids sensor operates based on the combined infrared absorption and scattering method. Infrared light emitted by the source is scattered by suspended particles in the sample, then converted into an electrical signal by a photoelectric detector. The signal undergoes analog and digital processing to determine the suspended solids concentration. 

Features

1. Operating on the scattered light principle with a built-in temperature sensor;

2. Supports RS-485 and Modbus/RTU protocols;

3. Optical fiber structure with strong resistance to external light interference;

4. Infrared LED light source for high stability;

5. IP68 waterproof rating, submersible up to 20 meters depth;

Installation

The sensor can't installed upside down or horizontally; it should be mounted at an angle of at least 15 degrees
