Online RDO Sensor


Product Introduction:

The RDO sensor is based on the principle of fluorescence quenching. It measures the phase difference between the excitation light and reference light, comparing it with internal calibration values to calculate the concentration of oxygen molecules. The dissolved oxygen analyzer is suitable for measuring dissolved oxygen in industries such as surface water, groundwater, wastewater, and industrial water.

Product Features:

Low maintenance costs, no need to replace membranes and electrolytes.

User-friendly, no electrode calibration required.

Optional cleaning device to reduce maintenance workload.

Good reproducibility and long-term stable operation.

Does not consume oxygen and has no flow rate limitations.

Optical measurement with fast response time.

Pollution-free and environmentally friendly testing.
