Applications
H2scan’s HY-OPTIMA® 700B series in-line, real time hydrogen-specific process analyzers are designed for ease of use, interface flexibility and true process control. The HY-OPTIMA 700B series is a solid-state sensor that is configured to operate in process gas streams with temperatures up to 60ºC. The HY-OPTIMA 700B series is ideal for hydrogen production and petrochemical applications where real-time measurements can enhance process plant efficiencies, diagnostics and maintenance management. The HY-OPTIMA® 700B Series inline hydrogen process analyzer is also designed for gas streams where real-time, hydrogen-specific measurements can enhance process plant efficiencies, improve yields, and reduce maintenance costs.

Reliable Data for AI and Analytics
Proprietary self-monitoring technology continuously validates sensor performance, delivering clean, accurate data your AI and predictive maintenance initiatives demand. Unlike sensors that fail silently and corrupt your data record, H2scan sensors alert you immediately if performance degrades—ensuring every data point is reliable for both today’s monitoring needs and tomorrow’s analytics.
