RS485 Online fluorescence dissolved oxygen sensor DOS transmitter

WQS-DOS series Online fluorescence dissolved oxygen sensor manual Product description This product is a device for measuring the dissolved oxygen concentration in solutions. It adopts the fluorescence measurement principle, which does not consume oxygen and requires no electrolyte. It has a built - in temperature sensor with an automatic temperature compensation function. The calibration function provides a simpler and more convenient calibration method. It can be widely used in industries such as water treatment, aquaculture, and environmental monitoring. Features The measurement range of dissolved oxygen is 0 - 20mg/L (0 - 200% saturation). RS485 communication DC 10 - 30V wide - voltage power supply It uses a fluorescence diaphragm with imported quality. It adopts the fluorescence measurement principle, which does not consume oxygen and requires no electrolyte. Basic parameters Measuring range 0-20mg/L (0-200% saturation) Measurement error ±3%FS；±0.5℃（25℃）
