The patented ORBISPHERE Thermal Conductivity sensor was developed for continuous measurement of H2 levels in the gas phase or dissolved in a liquid. The measurement technique combines a gas diffusion membrane with a solid-state gas thermal conductivity detector.
This sensor is suitable for applications involving off-gas, outlet gas, trace levels and reactor cooling water.
• Continuous H2 measurements
• Selective measurement, results unaffected by the presence of other gases
• Fast response time to increase plant productivity
• Compact design that fits easily into a process line or a flow chamber
