1.Product Introduction
The KNF-505 online multi-parameter water quality sensor adopts an integrated design, integrating water quality monitoring sensors such as dissolved oxygen, pH, ORP, conductivity/salinity, turbidity, and temperature. It is equipped with an automatic cleaning device, effectively reducing the product maintenance cycle and enhancing the stability and accuracy of product measurement. Reliable and easy to use, with convenient installation, it is suitable for online water quality monitoring in environmental protection monitoring, water supply and drainage, ecological environment and other fields. By adopting the RS-485 bus and Modbus/RTU communication protocol, data can be directly transmitted to the acquisition platform.
The online multi-parameter water quality sensor is equipped with an automatic cleaning device, which can set the automatic cleaning interval time and the number of automatic cleaning cycles to adapt to water of different cleanliness levels. The automatic cleaning device can effectively clean the surface of the sensor, prevent the adhesion of microorganisms, and greatly reduce maintenance costs. Each sensor is equipped with a quick-plug waterproof connector for easy disassembly and assembly.
The sensor protective cover at the front end is used to protect the internal sensors from damage. There are slots and holes around the protective cover, which can effectively prevent large suspended particles and organisms from damaging the sensor probe, while not affecting the measurement accuracy.
