Abstract
A device for measuring the thermal conductivity of a fluid comprising a first detection section with at least one duct in which a gas flows and at least one heat sensitive resistance element placed in that duct, and a second detection section for the detection of an electrical resistance of the heat sensitive resistance elements. The device also comprises a thermoregulator to maintain the first detection section at a constant first temperature and a further thermoregulator to maintain at least part of the second detection section at a constant second temperature independent of the first temperature.
