HY-OPTIMA™ 720 In-Line Process Hydrogen Analyzer (Oxygen & Nitrogen)

General Details

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™ 720 is a solid state sensor configured to operate in air background gas streams having up to 95% relative humidity and temperatures up to 60ºC. The HY-OPTIMA™ 720 is ideal for the monitoring of hydrogen processes where real time measurements of hydrogen can ensure safety in application, increase process efficiencies, improve diagnostics and enhance maintenance management translating into higher profitability.
