Key Features

• Five-gas mixture measurement: Designed to measure hydrogen in gas mixtures containing O₂, CO, CO₂, CH₄, and H₂.
• TCD-based hydrogen measurement: Uses the difference in thermal conductivity between hydrogen and other gases to determine H₂ concentration.
• Wide H₂ measurement range: Supports hydrogen measurement from ppm levels to percentage concentrations, depending on the configured application and range.
• Accurate H₂ calculation: Measurement and correction methods help ensure that the analyzer uses the correct settings to calculate hydrogen concentrations within complex gas mixtures.
• High thermal conductivity sensitivity: Hydrogen has a particularly high thermal conductivity, providing a strong basis for TCD measurement.
• Reference and sample gas comparison: The TCD compares the thermal conductivity response of the sample gas with a reference condition to determine changes caused by hydrogen.
• Electrical signal conversion: Changes in the thermal conductivity of the sample gas are converted into an electrical signal and correlated with H₂ concentration.
• Non-reactive measurement principle: TCD measurement is based on the physical thermal conductivity properties of the gas rather than a chemical reaction. This principle is widely used for continuous hydrogen measurement.
• Industrial gas analysis: Suitable for applications requiring accurate hydrogen measurement in multi-component process gas mixtures.
