Title (EN) GAS DETECTION ELEMENT
(FR) ÉLÉMENT DE DÉTECTION DE GAZ
(JA) ガス検知エレメント
Abstract:
(EN) This gas detection element for detecting gas to be measured has a spacer and a gas detection layer containing a chemochromic pigment. The spacer is permeable by the gas to be measured, is disposed on a first surface of the gas detection layer, and has a surface area smaller than that of the gas detection layer.
(FR) L'invention concerne un élément de détection de gaz pour la détection de gaz à mesurer comprenant une entretoise et une couche de détection de gaz contenant un pigment chimiochrome. L'entretoise est perméable au gaz à mesurer, est disposée sur une première surface de la couche de détection de gaz, et présente une surface plus petite que celle de la couche de détection de gaz.
(JA) 測定対象ガスを検知するガス検知エレメントであって、ケモクロミックピグメントを含有するガス検知層と、スペーサと、を有し、前記スペーサは、前記測定対象ガスに対する透過性を有し、前記スペーサは、前記ガス検知層の第1の表面上に配置され、該ガス検知層よりも小さな面積を有する、ガス検知エレメント。
