GAS MEASUREMENT METHOD, DEVICE AND INTERFERING GAS COMPENSATION DEVICE

A gas measurement method, comprising: during the measurement of the measured gas, extracting gas by a preset rule to conduct zero calibration measurement, and recording the zero calibration measurement result; determining a compensation value for the present measurement period according to historic zero calibration measurement results meeting a set conditions, extracting the measured gas for measurement, and obtaining the preliminary measurement result of the measured gas within the present measurement period; utilizing the compensation value of the present measurement period to compensate the measured preliminary measurement result of the measured gas, and obtaining the compensated measurement result of the measured gas. The present method compensates the interfering gas not by using an adsorbent but by obtaining a point least influenced by environmental interfering gas, and utilizing the point to calculate the concentration for compensation, thus reducing the influence of the environmental interfering gas on the measurement result of the measured gas.
