HY-OPTIMA™ 1700 Intrinsically Safe In-line Process Hydrogen Analyzer

General Details

H2scan’s HY-OPTIMA™ 1700 in-line, real time hydrogen-specific process analyzers are designed for ease of use, interface flexibility and true process control. The HY-OPTIMA™ 1700 is an intrinsically safe device that incorporates our patented solid-state sensor and is configured to operate in background gas streams with up to 95% relative humidity and temperatures up to 60ºC. The HY-OPTIMA™ 1700 is ideal for process gas streams containing virtually no contaminants and where real time continuous measurements of hydrogen can increase process plant efficiencies, improve diagnostics and enhance maintenance management translating into higher profitability.
