 HY-OPTIMA™ 2700 Process Hydrogen Analyzer

The HY-OPTIMA™ 2700 real-time hydrogen-specific process analyzers are designed for ease of use, interface flexibility and true process control. The HY-OPTIMA™ 2700 uses a solid-state sensor that is configured to operate in process gas streams. The 2700 line of analyzers includes models that can tolerate levels of carbon monoxide (CO) up to 20% by volume and levels of hydrogen sulfide (H2S) of up to 10% by volume. The HY-OPTIMA™ 2700 is ideal for hydrogen production and petrochemical applications where real-time measurements can enhance process plant efficiencies, diagnostics and maintenance management.
