Product Description

DO-6383YG dissolved oxygen sensor adopt fluorescence measurement of dissolved oxygen and emit blue light on the screen. The fluorescent substance is stimulated to emit red light. The oxygen concentration is inversely proportional to the time when the fluorescent substance returns to the ground state. The dissolved oxygen measured by this method does not produce oxygen consumption when measured, the data is stable, the performance is reliable, the interference is not exist, the installation and correction are simple.

The product is widely used in wastewater treatment plants, waterworks, water stations, surface water, aquaculture, industrial and other fields of dissolved oxygen monitoring. The configured waterproof high-performance controller can easily receive the data measured by the sensor. The user can also realize the 4-20mA analog output through the interface configuration and calibration of the controller. It realize relay control, digital communication and other function.
