LH-DY06 Online water quality monitoring series
Fluorescent Dissolved Oxygen Intelligent Sensor
According to the green light excitation fluorescence lifetime detection technology, the green light from the light emitting diode (LED) irradiates the fluorescent substance to excite the red light. Due to the quenching effect of the oxygen molecules in the water, the fluorescence lifetime of the excited red light is inversely proportional to the dissolved oxygen concentration in the water, so the dissolved oxygen concentration in the water can be calculated by measuring the excited red light fluorescence lifetime.
1. Green light excited fluorescence lifetime detection technology, no electrolyte, no maintenance, stable and reliable measurement
2. No oxygen consumption, no flow rate and agitation requirements.
3. Built-in temperature sensor with automatic water temperature compensation function
4. Support MODBUS/RS485,4-20mA current interface output
5. Sensors stainless steel surface dirt can be wiped with soft cloth.
6. Wipe the dirt on the outer surface of the fluorescent cap with a wet soft cloth after cleaning with water.Do not force
7. Check if the fluorescent cap is damaged when the data measurement deviation is large
8. When the sensor is in use, it is necessary to ensure that more than 1/3 of the water is immersed in the water sample to
