Yosemitech Y504-A Online Optical Dissolved Oxygen Sensor is an instrument used to measure the concentration of dissolved oxygen in water. The dissolved oxygen content in water is one of the important indicators for evaluating water quality and is crucial to the survival and health of aquatic organisms.
Our Optical Dissolved Oxygen Sensor adopts new generation of fluorescence lifetime technology. It uses high-performance fluorescent material, doesn't consume oxygen, has no flow rate restrictions, does not require electrolyte, is calibration and maintenance-free, is not affected by hydrogen sulfide, and demonstrates excellent accuracy and stability. Simultaneously, this DO sensor comes with an integrated temperature sensor and includes automatic temperature compensation.
Digital sensor, RS485 output, MODBUS protocol
No electrolyte required, strong anti-interference, no need for frequent calibration
No oxygen consumption, no flow rate limitation
Built-in temperature sensor, automatic temperature compensation
Built-in calibration parameters, accurately calibrated before delivery, ready for direct installation and use
