Online multi-parameter Water Quality Sensor
Applications
The multi-parameter water quality sensor (seven parameters) features an integrated design. Each sensor is outfitted with a waterproof connector, and the calibration data is securely stored within the sensor. This enables calibration and replacement to be carried out conveniently in the field. You have the flexibility to connect up to 6 water quality digital sensors simultaneously. The available options include fluorine dissolved oxygen, four electrode conductivity, fiber turbidity, digital pH, digital ORP, chlorophyll, water oil, and ammonia nitrogen sensors, providing a wide range of choices to meet diverse monitoring requirements.
It is equipped with a cleaning device that effectively eliminates air bubbles and acts as a safeguard against microbial growth. This sensor is well-suited for various water environment monitoring needs, such as those of rivers, lakes, oceans, and groundwater. It demonstrates excellent reliability, eliminating the need for maintenance and being capable of operating for several months in an unattended environment.
For instance, in a large-scale water treatment plant that monitors the quality of water from a nearby river, this multi-parameter sensor can continuously provide accurate data on multiple aspects, allowing for timely adjustments to the treatment process. In oceanographic research, it can collect comprehensive water quality information over an extended period without the need for constant human supervision. Similarly, for groundwater monitoring in agricultural areas, its long-term, maintenance-free operation helps in assessing the potential impact of agricultural activities on groundwater quality.
Feature
Digital sensor, RS485 output, support MODBUS, all calibration parameters are stored in the sensor, each probe has a waterproof connector, which can be easily plugged and replaced. Equipped with automatic cleaning function, it can effectively remove sensor surface contamination, prevent microbial growth, and be more accurate and less maintenance. Optional fluorescence dissolved oxygen, four-electrode conductivity, fiber turbidity, digital pH, digital ORP, chlorophyll, water oil and ammonia nitrogen sensors for long-term online monitoring. The all-in-one design allows for the simultaneous connection of six probes and seven parameters.
