Description

1. Introduction
Water quality sensor adopts an integrated structure design. It is specially designed for water quality instruments used for long-term online monitoring. The device can monitor four key water quality parameters in real time, including temperature, conductivity (salinity) and depth, providing accurate and efficient data support for coastal ecological research.
Adheres to the design philosophy of miniaturisation, high integration, and high performance, reducing the size and weight of the sensor while ensuring performance. This not only makes installation and deployment straightforward and convenient, but also facilitates on-site cleaning, thereby saving both time and costs. The sensor can withstand pressures equivalent to depths of up to 200 metres underwater and operate reliably, making it well-suited for monitoring diverse complex aquatic environments such as coastal waters, groundwater, lakes and reservoirs.


2.Sensor Features:
Digital sensor, RS485 output, standard MODBUS protocol.
Specifically designed for long-term online water quality monitoring, integrating four key parameter monitoring functions: temperature, conductivity (salinity) and depth.
While ensuring performance, the size and weight have been reduced for easy installation and deployment.
Supports on-site cleaning, user calibration, easy to operate.
