Abstract
(EN)
An aqueous solution of Na salt of phenolsulfonic acid polymer as a liquid electrolyte is held on a separator of liquid electrochemical gas sensor. A detection electrode and a counter electrode are connected to the separator, and CO is detected at about -40° to 70°C.
(FR)
Une solution aqueuse de sel de Na d'un polymère d'acide phénolsulfonique, formant un électrolyte liquide, est maintenue sur le séparateur d'un détecteur électrochimique liquide de gaz. Une électrode de détection et une contre-électrode sont connectées au séparateur, et le CO est détecté à une température comprise entre environ 40° et 70 °C.
(JA)
 フェノールスルホン酸ポリマーのNa塩の水溶液を液体電解質として、液体電気化学ガスセンサのセパレータに保持させる。セパレータに検知極と対極を接続し、−40°C~70°C程度でCOを検出する。
