Product Overview<\/b><\/strong><\/h3>\n

The In-situ High-Temperature Humidity & Oxygen Analyzer is a high-performance instrument designed for online monitoring of flue gas humidity and oxygen concentration in high-temperature and highly corrosive environments. It utilizes solid-state electrolyte ceramic sensor technology combined with the limiting current method for humidity measurement, enabling stable operation at temperatures up to 500\u00b0C.<\/p>\n

With excellent corrosion resistance and high measurement accuracy, the analyzer meets the requirements of HJ 75-2017 and HJ 76-2017 standards. It ensures reliable performance even under harsh conditions involving heavy metals, high humidity, and complex organic interference, making it ideal for environmental and industrial emission monitoring applications.<\/p>\n

Working Principle<\/b><\/strong><\/h3>\n

The analyzer integrates zirconia-based solid electrolyte sensing with the limiting current method to achieve simultaneous measurement of oxygen and humidity:<\/p>\n

    \n
  • Oxygen Measurement<\/strong>: The zirconia sensor generates an electrochemical signal at high temperatures, which is proportional to the oxygen concentration.<\/li>\n
  • Humidity Measurement<\/strong>: The limiting current method measures water vapor content, which is then converted into volumetric percentage through built-in algorithms.<\/li>\n<\/ul>\n

    The sensor operates in direct contact with the flue gas at high temperature, enabling true in-situ measurement. This eliminates sampling-related errors and ensures faster response and higher accuracy.<\/p>\n
