Abstract
A gas analyzer comprising a Wheatstone bridge, consisting of resistance wires, which are provided in two mutually separated channels of a measuring block. The resistance wires of opposite legs of the bridge are contained in the same channel, wherein a reference gas may be conducted through a first one of said channels and a gas to be analyzed may be conducted through a second one of said channels. The current through the bridge is controlled during a measurement in such a manner that the resistance of the resistance wires in the second channel remains substantially constant.
