Thermal Conductivity

Operating Principle: Based on the characteristic of high thermal conductivity, the hydrogen concentration analyzer by thermal conductivity detection determines the concentration by detecting the change in thermal conductivity of the gas. In the instrument, a thermistor element is exposed to the gas to be measured. The change in concentration leads to a change in thermal conductivity, which in turn causes a temperature change in the thermistor. The instrument calculates the concentration by measuring the change in resistance.
