YOSEMITECH's Y504-A online dissolved oxygen sensor is a device used for measuring the level of dissolved oxygen in water. It adopts a new generation of fluorescence lifetime technology. The fluorescence dissolved oxygen sensor operates on the principle of active fluorescence quenching by specific substances in physics. It doesn't consume oxygen and is not limited by flow rate.
It is widely used in environmental monitoring, groundwater monitoring, marine research, wastewater treatment and other fields.
Features
Digital sensor, Modbus RS485 interface
No membrane, no electrolyte, easy sensing cap replacement
No oxygen consumption, no flow dependency, no H2S interference
Embedded temperature for automatic temperature compensation
