Fluorescence DO Meter Sensor 12 24V Waterproof Freshwater

Meet the Fluorescence DO Meter Sensor 12-24V Waterproof Freshwater — a rugged, high-precision dissolved oxygen meter designed for aquaculture, environmental monitoring, and water treatment. Its fluorescence-based sensor translates the oxygen content of water into a reliable signal, delivering measurements for dissolved oxygen, saturation, oxygen partial pressure, and temperature with impressive accuracy. The device is waterproof (IP68) and built to operate reliably in harsh aquatic environments, enabling continuous online monitoring and remote data logging via RS-485 or compatible recorders.

Designed for easy integration, the prefabricated threads simplify installation and fixation, while the fluorescence probe itself does not consume oxygen and is immune to magnetic interference. This means stable, real-time readings even in dynamic systems. The instrument supports automatic temperature compensation and two-point calibration for optimum performance, making it a dependable choice for ponds, aquaculture facilities, wastewater treatment, and industrial processes.
