Dissolve Oxygen Sensor

Overview

Dissolved Oxygen (DO) Sensor is a precision instrument used to measure the concentration of oxygen dissolved in liquids, which is critical for assessing water quality and biological activity. The sensor operates using optical or electrochemical technology to provide accurate, real-time readings. It plays an essential role in applications such as wastewater treatment, aquaculture, environmental monitoring, and laboratory analysis, where maintaining proper oxygen levels is vital for process efficiency, regulatory compliance, and ecological balance. With modern digital interfaces and low-maintenance designs, DO sensors offer reliable performance in both field and industrial environments.
