Zusammenfassung: | To provide a gas detector having a plurality of flow passages branching from one common gas introduction port, the gas detector being capable of correcting gas of a sensor for each flow passage.SOLUTION: A gas detector 1 includes: a plurality of flow passages with at least one sensor formed in between; a branch flow passage 53 connected to one gas introduction port 12 at one end and branching into at least two passages on the other side; a gas flow passage into which a correction gas flows; and a flow passage formation unit in which a branch flow passage and a correction gas flow passage are formed. The flow passage formation unit can switch the state of connecting the plurality of flow passages and the branch flow passage together and the state of connecting the correction gas flow passage and one of the plurality of flow passages.SELECTED DRAWING: Figure 5
【課題】一の共通のガス導入口から分岐した複数の流路を有するガス検出器であっても、流路ごとにセンサのガス校正を行うことができるガス検出器を提供すること。【解決手段】1以上のセンサが介設された複数の流路と、一のガス導入口12に一端側で接続するとともに他方側では2以上に分岐する分岐流路53と、校正ガスが流入する校正ガス流路と、分岐流路及び校正ガス流路が形成された流路形成部とを備えたガス検出装置1であって、流路形成部が、複数の流路と分岐流路とを接続する状態と校正ガス流路と前記複数の流路のうち一の流路とを切り替え可能であるように、流路形成部が構成されたこと。【選択図】図5 |
