PROBLEM TO BE SOLVED: To provide a gas detector with which it is possible to prevent the output value of a continuous drive type sensor from being affected each time an intermittent drive type sensor is intermittently driven.SOLUTION: Provided is a gas detector X comprising at least two or more sensors S including an intermittent drive type sensor 10 and a continuous drive type sensor 20, a reference voltage unit 30 capable of outputting a DC voltage stably, a control unit 40 capable of recognizing the output value of each sensor S and the voltage value of the reference voltage unit 30, and a display unit 50 capable of displaying the output value of each sensor S, the control unit 40 calculating a differential voltage value between the voltage value of the reference voltage unit 30 when electricity to the intermittent drive type sensor 10 is turned on and the voltage value of the reference voltage unit 30 when electricity to the intermittent drive type sensor 10 is not turned on, and further making a correction value in which the differential voltage value is reflected in the output value obtained from the continuous drive type sensor 20 displayed by the display unit 50.SELECTED DRAWING: Figure 1 【課題】間欠駆動式センサの間欠駆動の度に、連続駆動式センサの出力値に影響を及ぼすのを未然に防止できるガス検知器を提供する。【解決手段】間欠駆動式センサ１０および連続駆動式センサ２０の少なくとも二つ以上のセンサＳと、直流電圧を安定して出力できる基準電圧部３０と、各センサＳの出力値および基準電圧部３０の電圧値を認識できる制御部４０と、各センサＳの出力値を表示できる表示部５０と、を備え、制御部４０は、間欠駆動式センサ１０を通電したときの基準電圧部３０の電圧値、および、間欠駆動式センサ１０に通電しないときの基準電圧部３０の電圧値の差分電圧値を算出し、さらに連続駆動式センサ２０から得た出力値に差分電圧値を反映させた補正値を表示部５０に表示させるように制御するガス検知器Ｘ。【選択図】図１
