Trace Oxygen Analyzer

Product Overview

The trace oxygen analyzer adopts advanced limiting current zirconia sensor technology and is specifically designed for ppm-level oxygen measurement in industrial processes.

It offers high accuracy, fast response, and excellent stability, ensuring reliable long-term operation even under demanding conditions. With a compact modular design and user-friendly interface, the analyzer provides a precise and stable solution for oxygen monitoring in both industrial and research applications.

Working Principle

The analyzer operates based on a limiting current zirconia sensor. At elevated temperatures, zirconia exhibits selective conductivity to oxygen ions.

When the sample gas passes through the sensor, oxygen molecules undergo electrochemical reactions at the electrode surface, generating a limiting current signal proportional to the oxygen concentration. This signal is processed by the system to achieve accurate ppm-level oxygen measurement.

Temperature control and signal compensation technologies are applied to ensure stable and reliable measurement results.
