および異なる酸素濃度を持つ標準ガス２種の計３
系統の標本ガスの一つを選ぶ切替弁手段と、選ん
だガスを吸引して酸素濃度の測定手段に導く手段
と、一定の時間間隔で標本ガスの選択を切り替え
て、２種の標準ガスの測定から得られる値から測
定値の校正に必要な係数を算出する手段を備えた
酸素濃度測定方法。 A total of 3 methods for measuring the oxygen concentration of gas, a gas to be measured, and 2 standard gases with different oxygen concentrations.
A switching valve means for selecting one of the sample gases in the system, a means for sucking the selected gas and guiding it to the oxygen concentration measuring means, and switching the selection of the sample gas at regular time intervals to select one of the two standard gases. An oxygen concentration measurement method that includes means for calculating the coefficients necessary for calibrating the measured values from the values obtained from the measurements.
