Product Overview
The Ultraviolet Hydrogen Sulfide Analyzer adopts advanced UV absorption spectroscopy technology for high-precision, real-time monitoring of H₂S. With a built-in high-precision gas cell and dedicated algorithms, the instrument minimizes cross-interference from other gases and provides accurate online H₂S concentration measurements. Featuring long service life, low maintenance, and high cost-efficiency, it is ideal for continuous industrial monitoring, outperforming traditional electrochemical sensors or gas chromatography in both reliability and operational convenience.
Working Principle
The analyzer is based on ultraviolet absorption spectroscopy, measuring the absorption intensity of H₂S at specific UV wavelengths to determine gas concentration in real time. Equipped with an automatic zeroing pump and a corrosion-resistant gas cell, the system ensures stable and reliable measurements. It also supports multiple data interfaces for remote monitoring and centralized management.
