In-Situ High-Temperature Humidity & Oxygen Analyzer

Product Overview
The In-Situ High-Temperature Humidity & Oxygen Analyzer adopts internationally advanced solid-state ceramic electrolytic sensor technology for wet and dry oxygen measurement, combined with the extreme current measurement method for humidity. It is specifically designed for online monitoring of flue gas humidity and oxygen concentration in high-temperature and highly corrosive environments. This instrument can operate stably in temperatures up to 500°C and features excellent corrosion resistance, fast response, and high-precision measurement capabilities. It is particularly suitable for harsh conditions involving volatile organic compounds (VOCs) that contain heavy metals, high corrosion, high humidity, and complex organic interference. Compliant with the HJ 75-2017 and HJ 76-2017 standards, it is widely used for online measurement of flue gas humidity and oxygen to ensure compliance with environmental protection regulations.

Key Features

• High-Temperature Tolerance: The core sensor is designed with high-temperature resistance, withstanding temperatures up to 500°C, ensuring stable long-term operation in high-temperature environments.
• High-Precision Measurement: Both humidity and oxygen content are output as volume percentages. Humidity precision is ±2%F.S, and oxygen precision is ±1%F.S, meeting environmental protection technology standards.
• Strong Corrosion Resistance: Utilizing solid-state ceramic electrolytic sensor technology, the instrument offers excellent corrosion resistance, making it ideal for harsh, corrosive environments with a long service life.
• Fast Response: The response time is short, with T90 < 20 seconds, ensuring rapid and real-time data feedback.
• Convenient Calibration Function: Features a one-click calibration function for air, simplifying and improving calibration efficiency.
• Flexible Installation and Application: Supports insertion-type installation and allows for customized flange specifications and probe lengths to meet different flue gas or operational requirements.
• Multiple Calibration Functions: Supports zero point and range calibration for both oxygen and humidity, ensuring long-term stable operation.
