Page 9: Introduction
Figure 1 501 Analyzer and Transmitter The XTP501 Analyzer is based on Michell Instruments’ advanced proprietary Thermo- Paramagnetic technology. It measures the percentage of oxygen in a wide range of gases, including nitrogen, hydrogen, carbon dioxide, methane and biogas. The XTC501 Analyzer uses our thermal conductivity sensor to measure a target gas such as hydrogen in a background gas such as nitrogen. -
Page 10: Sensor Technologies
INTRODUCTION XTP501 & XTC501 User’s Manual Sensor Technologies 1.1.1 Thermo-paramagnetic Michell’s thermo-paramagnetic sensor uses a combination of paramagnetic and thermal conductivity techniques to accurately measure the oxygen content within a process gas. Oxygen is a paramagnetic gas, which means that it is attracted to a magnetic field. It is this property that can be exploited to help determine the level of oxygen in many background gases. -
Page 11: Thermal Conductivity
XTP501 & XTC501 User’s Manual INTRODUCTION 1.1.2 Thermal Conductivity Thermal conductivity (TC) is a property of all gases. This can be exploited as each gas has a different TC value and is used to determine the level of one gas in a binary or pseudo-binary mix. -

Has the equipment been cleaned and decontaminated? NOT NECESSARY Michell Instruments will not accept instruments that have been exposed to toxins, radio-activity or bio-hazardous materials. For most applications involving solvents, acidic, basic, flammable or toxic gases a simple purge with dry gas (dew point <-30°C) over 24 hours should be sufficient to decontaminate the unit prior to return. - Page 56 http://www.michell.com...
