The H2scan is an explosion-proof in-line hydrogen process analyzer

With a solid-state, non-consumable sensor configured to operate in process gas streams, the H2scan hydrogen process analyzer uses thin film technology to provide a direct hydrogen measurement that is not cross-sensitive to other gases.


A hydrogen process analyzer with a solid-state, non-consumable sensor configured for process gas streams

The H2scan hydrogen process analyzer features thin film technology that provides a direct hydrogen measurement that is not cross-sensitive to other gases. The H2scan is ideal for applications where real-time, hydrogen specific measurements can enhance process efficiencies, diagnostics and maintenance management.

The H2scan does not require significant application development for each mix of hydrocarbon gases, yet it still exceeds industry standards.

Seamlessly combines with the SpectraScan 2400

Used as a complement to the light hydrocarbon analysis capability of the SpectraScan 2400, the combination of two innovative technologies challenges traditional Gas Chromatography analysis.

By producing an accurate measurement at considerably faster speed, the H2scan/SpectraScan 2400 combination is a superior, yet simpler, detection for recycled and waste gas, and heating valve applications, achieved at considerably lower implementation and product lifetime costs.
