Abstract
En karbondioksid-sensor omfatter et lukket kammer som har som en vegg en hovedsakelig vanntett, karbondioksid-permeabel membran (3) og inneholder to elektroder (5, 6). Kammeret inneholder en film (9) av deionisert vann som berører membranen (3) og begge elektroder. Forandringen i konduktans for vannet på grunn av absorpsjon av karbondioksid blir målt.
