The present invention relates to agas regulating device (2A-E) for use in calibration of a gas analyzer (4). The gas regulating device comprises an inlet (8A) and an outlet (8B), a valve arrangement comprising at least one valve (11; 11A, 11B), and valve regulating means for regulating the at least one valve. The gas regulating device is intended to be connected between a calibration gas supply (3) and a gas analyzer (4) that is to be calibrated and the valve regulating means is configured to regulate the at least one valve such that gas is allowed to flow through a gas flow path (5B) between the inlet and outlet only when a gas pressure (P1)in the gas flow path, between the at least one valve and the outlet, falls below a predetermined threshold value. The gas regulating device is advantageously used when calibrating side-stream gas analyzers in which case it reduces calibration gas consumption, prevents discharge of calibration gas into the ambient environment and prevents leakages jeopardizing correct calibration.
