Multi-parameter water quality analyzer
The online dissolved oxygen sensor uses fluorescence technology to measure dissolved oxygen in water. It features a built-in temperature sensor for automatic temperature compensation and supports manual compensation for air pressure and salinity. The sensor communicates via RS485 interface with standard Modbus protocol.
● Power isolation design ensures stable signals without interference
● Standard Modbus-RTU protocol for simple and convenient integration
● Low-power consumption design
● RS485 interface with ModBus protocol for seamless integration.
