How to choose the type of dissolved oxygen meter

The dissolved oxygen meter is a device for measuring dissolved oxygen in water. Its working principle is that oxygen passes through the diaphragm and is reduced by the working electrode, generating a diffusion current proportional to the oxygen concentration. By measuring this current, the concentration of dissolved oxygen in water is obtained.

How to choose the type of dissolved oxygen meter:

There are pen-type do meter, portable do meter, desktop do meter and industrial do meter. Which one to choose depends mainly on your usage scenario. Pen-type dissolved oxygen meters are generally single-range, with a small measurement range but a relatively low price. Portable dissolved oxygen meters have more functions than pen-type meters and are suitable for non-fixed working environments. Desktop dissolved oxygen meters are the most commonly used type in laboratory environments. Industrial dissolved oxygen meters have good stability, reliable operation, and strong environmental adaptability, and are generally used in industrial production environments.

The dissolved oxygen do meter is an common instrument for measuring dissolved oxygen in water. It is widely used for the measurement of dissolved oxygen in aquaculture farms, water plants, sewage treatment, environmental protection monitoring and scientific research institutes.
