What is dissolved oxygen? Dissolved oxygen (DO) refers to molecular oxygen dissolved in water. The unit is mg/L, which means how many milligrams oxygen in
Dissolved Oxygen Meter
Our RS-LDO-N01 dissolved oxygen meter is a device for measuring the concentration of dissolved oxygen in water. It adopts the principle of fluorescence measurement, does not consume oxygen, and does not require electrolytes. The dissolved oxygen measurement range is 0~20mg/L. Built-in temperature transmitter with automatic temperature compensation function.

About - Dissolved oxygen meter
Our dissolved oxygen sensors are divided into two types: seawater and freshwater. The calibration function provides a simpler and more convenient way to calibrate. Water dissolved oxygen meter can be widely used in water treatment, aquaculture, rivers, lakes, and seawater quality monitoring industries.

Working Principle - DO meter
Fluorescence Dissolved Oxygen: Based on the quenching principle of active fluorescence by specific substances in physics.
By measuring the phase difference between the excited red light and the reference light, and comparing it with the internal calibration value, the concentration of oxygen molecules can be calculated.
Long-term rainfall and melting snow have raised water levels and flooded city roads, causing flooding. Frequent and extreme flooding is inevitable and endangers community safety.
