Sensors

Dissolved ozone sensors are specialized instruments designed to measure the concentration of ozone (O₃) in water. Ozone is a strong oxidant widely used in water treatment, aquaculture, food processing, and industrial applications to disinfect water, remove contaminants, and improve water quality. Accurate measurement of dissolved ozone is critical to ensure both effectiveness and safety, because ozone can be harmful at high concentrations.

If you work with water systems — whether in aquaculture, hydroponics, greenhouses, environmental monitoring, or marine research — you’ve probably seen both conductivity and salinity used in dashboards and sensor specs.

They’re closely related.
They are often displayed side-by-side.
But they are not the same thing.

Understanding the difference helps you choose the right sensor, interpret your data correctly, and avoid costly mistakes.

Dissolved oxygen (DO) sensors are instruments used to measure the amount of oxygen dissolved in water. They are a critical tool in agriculture, aquaculture, hydroponics, water treatment, and industrial water systems, where oxygen levels directly affect biological activity and system performance.

Learn how to measure, record, and share water quality parameters like pH, DO, COD, and turbidity so you can choose the right system for your needs.
