Hybono ODO series portable fluorescence dissolved oxygen sensor (HY506-A) adopts a new generation of fluorescence lifetime technology and is a fluorescent material independently developed by Hybono. No oxygen consumption, no flow rate limitation, no electrolyte required, no maintenance and calibration, no hydrogen sulfide interference, and excellent stability. Built-in temperature sensor, automatic temperature compensation.
Overview
The Hybono dissolved oxygen sensor adopts the world's leading fluorescence lifetime technology, which is based on the quenching principle of active fluorescence by specific substances in physics. There is no oxygen consumption during the measurement process, so there is no flow rate limitation, and there is no need for preheating and no electrolyte. It is free of maintenance and frequent calibration, and the response time is as low as 30 seconds. Widely used in aquaculture monitoring, groundwater monitoring, marine research, wastewater treatment and other fields. Built-in temperature sensor, automatic temperature compensation. RS485 output, support MODBUS, can be easily integrated into water quality monitoring system to meet customer needs.
Working principle
The fluorescent dissolved oxygen sensor is based on the quenching principle of active fluorescence by specific substances in physics. The blue light from a light emitting diode (LED) irradiates the fluorescent material on the inner surface of the fluorescent cap, and the fluorescent material on the inner surface is excited to emit red light. Compare to calculate the concentration of oxygen molecules, and output the final value after automatic compensation of temperature and air pressure
