PT605 Series Gas Analyzers

Continuous Gas Analyzers - CO2 & H2S

Our dependable and cost-effective on-stream process gas analyzers are meticulously designed to accurately detect hydrogen sulfide (H2S) and carbon dioxide (CO2) in process streams and natural gas pipelines – including current gas concentration, the last successful calibration date and time, and the current alarm status. Our H2S process analyzer and our CO2 process analyzer come with standard 4-20mA outputs and three programmable alarm relay contacts for shut-in valves. In addition, our process gas analyzers feature large and back light LCD displays, easy-access push-button switches on the front, and the ability to log historical data.
