Online fluorescence dissolved oxygen sensor manual
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.
