CHINA PROBEST Wholesale Factory Dissolved Oxygen Probe Sensor Meter in Water

Dissolved oxygen is an important indicator that reflects the self-purification ability of water. In the past 50 years, the current method and polarography method have been used to measure dissolved oxygen. This has played a very important role in the monitoring of dissolved oxygen in municipal and industrial wastewater. However, traditional electrochemical probes use membranes, electrodes and electrolytes, which will cause many problems, such as the need for regular maintenance, and they are easily affected by gas and contained water in the water. The influence of salt content cannot get accurate measurement results.


Our probes are using innovative new fluorescent technology, no membrane, no electrolyte, almost no maintenance, excellent performance, easy to use; no oxygen consumption, fast response time, no reference electrode, no magnetic field interference, etc., more and more favored by many people in the field of water quality monitoring.


Fuzhou PROBEST is a professional manufacturer specializing in R&D, production and service of sensors, instruments and automation equipment. The fluorescent dissolved oxygen sensors independently developed and produced by our company all adopt Highest level fluorescent caps, which are of guaranteed quality and can be applied to a variety of working conditions.
