H2O Gas Analyzer

The CIRAS-3 SC is a lightweight, robust instrument with a rugged aluminum and polyurethane enclosure making it an ideal instrument for both field and lab. It features a high performance, absolute CO2 and H2O gas analyzer for measurement of a single gas stream. Our innovative “Auto Zero” measurement principle ensures long term stability and accuracy of both CO2 and H2O which is a significant advantage over “gas switching” systems. The gas analyzers include an infrared source, highly polished and gold plated sample cells and specially selected detectors optimized for CO2 and H2O. The optical bench is temperature controlled and pressure compensated ensuring the most accurate CO2 and H2O measurements under changing ambient conditions.
