Oxygen Meter

Product Introduction

The Oxygen Analyzer is a high-precision instrument designed for continuous and real-time measurement of oxygen concentration in gases or molten metals. Built for use in demanding environments such as steelmaking, combustion control, heat treatment, and environmental monitoring, this analyzer ensures optimal process efficiency, safety, and product quality.

Whether used in a high-temperature furnace or a low-oxygen atmosphere, the Oxygen Analyzer delivers accurate, fast, and reliable results, enabling industries to make data-driven process decisions.

The oxygen concentration diagram of molten steel: As shown in the figure above, the oxygen content is measured using a two-channel temperature curve to collect the comprehensive results of the temperature and oxygen potential in molten steel. The temperature capture accuracy is ±1℃. Finally, the oxygen content of molten steel is calculated based on the temperature platform temperature and oxygen potential.

Product Features
