Abstract

Fremgangsmåte og innretning for å måle innhold av oppløst i sjøvann, der - en pH-måling blir tatt med kolorimetri på en oppløsning hvis C02-konsentrasjon blir utjevnet til den i sjøvannet, en måling blir tatt ved en bølgelengde (XM) som er karakteristisk for en absorpsjonstopp av den basiske formen til fargen, - en supplerende måling blir tatt ved en bølgelengde (XB) som fargen ikke absorberer, en supplerende absorbansmåling blir tatt ved bølgelengden (XI) nær isobestisk punkt til fargen. Innretningen omfatter en målecelle som inneholder oppløsningen med fargelndikator og anordninger for suksessiv filtrering av optisk stråle ved utgangen av cellen ved forskjellige bølgelengder som er nødvendig for å gjennomføre målingene i henhold til prosessen.
