Dissolved oxygen detector DOY20A-S

fluorescencemonitoringfor wastewater treatment

The dissolved oxygen sensor uses the fluorescence method to measure the dissolved oxygen. The emitted blue light shines on the fluorescent layer, and the fluorescent substance is excited to emit red light, and the oxygen concentration is inversely proportional to the time for the fluorescent substance to return to the ground state. By using this method to measure the dissolved oxygen, there is no oxygen consumption during the measurement, the data is stable, the performance is reliable, there is no interference, and the installation and calibration are simple. This product is widely used in the dissolved oxygen monitoring of wastewater treatment plants, water supply plants, water stations, surface water, aquaculture, industry, and other fields. FEATURES • The sensor has no membrane and no electrolyte • It does not consume oxygen and has no flow rate limit • The built-in temperature sensor automatically compensates for the temperature • Modbus RTU digital communication, anti-interference, greatly improving stability and accuracy TECHNICAL PARAMETERS 线条.png Dissolved-oxygen-sensor.jpgRange:0-20mg/L(0-20ppm) (range can be customized) Temperature:0-45℃ Accuracy: ±3% of measured value Temperature: ±0.5℃ Storage temperature: -15 to60°C Measuring environment temperature: 0 to 45 °℃ (no freezing) Pressure range:≤0.3Mpa Calibration: Automatic air calibration Supply voltage:Wide voltage range 9-36VDC,recommended 12VDC Power consumption:0.6W Size: Diameter 49.5mm * Length 251.3mm Main materials: SUS316L (regular version), titanium alloy (seawater version) O-ring: Fluororubber Cable: PVC Waterproofrating: IP68/NEMA6P
