The KWS-850 on-line multi-parameter sensor for ammonia nitrogen and pH measurement
Product Description
The KWS-850 on-line multi-parameter sensor is a revolutionary device meticulously designed for accurate ammonia nitrogen and pH measurement. It stands out in the market with its advanced technology and reliable performance.
When it comes to ammonia nitrogen detection, it employs a highly sensitive sensing mechanism that can precisely quantify even trace amounts of this crucial parameter. This is of utmost importance in aquatic environments as excessive ammonia nitrogen can endanger aquatic life. For pH measurement, it features a precision electrode that provides instant and accurate readings, allowing for real-time monitoring of the acidity or alkalinity of water bodies.
Its on-line functionality enables seamless integration into existing water quality monitoring systems. Whether in wastewater treatment plants, aquaculture facilities, or environmental research projects, the KWS-850 ensures continuous, high-quality data acquisition, making it an essential tool for maintaining water quality and ecological balance.
Feature
- Digital sensor, RS-485 bus, Modbus/RTU communication protocol.
- Integrated design, can measure 8 parameters (including temperature) at the same time.
- Optional digital sensors such as dissolved oxygen, COD, conductivity/salinity, turbidity, ammonia nitrogen, pH, ORP, etc., suitable for long-term online monitoring.
- Equipped with an automatic cleaning device, it can effectively clean the surface of the sensor, prevent microorganisms from attaching, measure more accurately, and lower maintenance costs.
Dimension
Note: When the sensor is installed for measurement, use lifting rings or pipe thread installation to avoid direct force on the cable. The sensor connector is M16-5 core waterproof male connector.
