HY-OPTIMA™ 730 In-line Process Hydrogen Analyzer (ppm H2S & CO)

H2scan’s Series 700 in-line, real-time hydrogen specific process analyzers are designed for ease of use, interface flexibility and true process control. The HY-OPTIMA™ 730 is a solid-state sensor configured to operate in background gas streams having carbon monoxide concentrations up to 100 ppm, hydrogen sulfide stream concentrations up to 1000 ppm, up to 95% relative humidity, and temperatures up to 60ºC. The HY-OPTIMA™ 730 is ideal for hydrogen production and petrochemical applications where real-time measurements of hydrogen can increase process plant efficiencies, improve diagnostics and enhance maintenance management translating into higher profitability.
