Answer / nirmal

It functions by having two parallel tubes both containing
gas and heating coils. The gases are examined by comparing
the rate of loss of heat from the heating coils into the
gas. The coils are arranged in a bridge circuit so that
resistance changes due to unequal cooling can be measured.
One channel normally holds a reference gas and the mixture
to be tested is passed through the other channel
