ความช่วยเหลือ
The unique Orbisphere Thermal Conductivity sensor has been developed to give continuous H2 measurements in gas phase or dissolved in a liquid. The measuring technique is a combination of a gas diffusion membrane and a solid-state gas thermal conductivity detector.
A micro volume enclosed between a semi-permeable membrane and a thermal conductivity detector is periodically flushed with a purge gas. After each purge, the gas to be measured diffuses from the sample through the membrane, changing the thermal conductivity of the gas surrounding the detector. A change in thermal conductivity modifies the detector resistivity. This is measured, together with temperature, to calculate the gas concentration.

• Continuous H2 measurements
• Selective measurement, result unaffected by the presence of other gases
• Fast response time to improve plant productivity
• Compact design for easy insertion into a process line or a flow chamber
