PROBLEM TO BE SOLVED: To obtain an accurate gas measurement corresponding to a measurement environment without additionally providing an atmospheric pressure measuring device such as a pressure sensor.SOLUTION: A measuring section 12 obtains a measurement for a predetermined parameter of gas to be measured. An altitude acquisition section 14 acquires altitude information indicating an altitude of an installation place. An atmospheric pressure calculation section 15 calculates atmospheric pressure in the installation place on the basis of the altitude information. A correction section 13 corrects the measurement on the basis of the calculation value of the atmospheric pressure.COPYRIGHT: (C)2013,JPO&INPIT【課題】圧力センサ等の気圧測定装置を追加装備することなく、測定環境に応じた正確なガス測定値を得る。【解決手段】測定部12は、被測定ガスの所定パラメータについて測定値を得る。標高取得部14は、設置場所の標高を示す標高情報を取得する。気圧算出部15は、前記標高情報に基づいて前記設置場所における気圧を算出する。補正部13は、前記気圧の算出値に基づいて前記測定値を補正する。【選択図】図1
