What is a Dissolved oxygen meter?

The dissolved oxygen meter is a device that measures and displays the amount of dissolved oxygen dissolved in the liquid. Some items are portable and easy to carry, others are installed and fixed at the place where you want to measure dissolved oxygen, and others can send the signal to a centralized control device such as DCS and display it in real time. Dissolved oxygen meters are used, for example, in managing the operating status of wastewater treatment facilities and in various food factories, using the amount of dissolved oxygen as an index in wastewater treatment factories.

Application of Dissolved oxygen meter

Dissolved oxygen meters are often used to display indicators of water pollution in wastewater treatment facilities. Aerobic treatment, which is used in many factories in Japan, is a wastewater treatment that uses aerobic organisms that consume oxygen when decomposing dirt in water. As the name implies, this method requires oxygen, so if the water is depleted of oxygen, effective wastewater treatment will not be possible. Therefore, the dissolved oxygen meter always measures the dissolved oxygen concentration in water. In addition, in the food industry, the fermentation condition of fermented foods is measured with a dissolved oxygen meter.
