Refineries and petrochemical plants use and produce hydrogen throughout hydroprocessing, reforming and treating — in hazardous areas where safety ratings and accuracy are non-negotiable. H2scan’s HY-OPTIMA analyzers measure hydrogen directly in the process stream and hold accuracy against the complex background gases these units generate, without the false readings or support equipment other technologies demand. Intrinsically safe and explosion-proof options are available for classified areas, so the same trusted measurement covers safety, process control and optimization.

Decades
of industrial hydrogen expertise
From a single unit to a whole refinery, H2scan helps you place hazardous-area-rated analysis and integrate it with your DCS.
Decades of hydrogen expertise. 1.3+ billion sensor hours in the field. Self-calibrating, hydrogen-specific solid-state sensing, with experts at your side.
Process hydrogen measurement is only useful if it stays accurate in real conditions. H2scan’s solid-state sensing detects hydrogen against virtually any background gas, so readings hold up in the streams refineries actually run.
With intrinsically safe and explosion-proof options, the same reliable measurement serves classified areas — supporting worker safety, process control and optimization without consumables or routine calibration.
Intrinsically safe and explosion-proof options for classified areas.
Cross-sensitivity-free sensing holds accuracy against background gases.
Early detection of hydrogen where it can accumulate around units.
Steady, trustworthy measurement supports control and yield.
4–20mA and Modbus outputs feed plant control systems.
Self-calibrating analysis that reduces upkeep.
Share your units and area classifications and an H2scan expert will scope the right analyzers and integration.
A. With continuous inline analyzers that read hydrogen directly in the stream. H2scan’s HY-OPTIMA analyzers hold accuracy against the complex background gases of hydroprocessing and reforming, without false readings or expensive support equipment.
A. H2scan offers intrinsically safe and explosion-proof HY-OPTIMA options rated for classified areas, so the same reliable measurement can be deployed safely around process units. Confirm the exact rating per product for your area classification.
A. HY-ALERTA area monitors provide continuous coverage where hydrogen can accumulate, giving early warning to protect people and the plant.
A. Sensors that respond to other gases produce false readings that can trip alarms or shut down a process. H2scan’s coating responds to hydrogen alone, so measurement stays trustworthy in complex streams.
A. Yes. HY-OPTIMA analyzers output over 4–20mA and Modbus and feed plant DCS, safety systems and the H2cloud platform.
