Definition of katharometer in English:

katharometer

noun

  • An instrument for detecting a gas or measuring its concentration in a mixture, by measuring changes in thermal conductivity.

    • ‘In construction the katharometer comprises two chambers, each with an identical thermal conductivity sensor.’
    • ‘The properties of katharometers are described in relation to the analyses of binary and multi-component gas mixtures.’
    • ‘This sensor is compact and reliable for use in the cover gas hydrogen meter in place of the katharometer.’
    • ‘Consequently, all katharometer detectors must be carefully thermostatted and must be fitted with reference cells to help compensate for changes in pressure or flow rate.’
    • ‘In recent communications the relative effects of gases of high and low thermal conductivity on the response of katharometers to the presence of eluted substances have been considered.’
