Condumax II On-Line koolwaterstof-dauwpunt analyser

Condumax II on-line is een volledig onafhankelijke koolwaterstof-dauwpunt analyser. Het meetprincipe wordt met de bewezen “Dark Spot” koolwaterstof-dauwpunt technologie gedaan die ook gebruikt wordt in de succesvolle Condumax. In de Condumax II on-line is een koolwaterstof-dauwpunt sensor gecombineerd met waterdauwpuntmeting in één compacte en lichtgewicht EExd behuizing. Voor de meting is alleen nog netvoeding nodig

Geschikt voor gebruik in aardgas dat tot 20% waterstof bevat. Geen modificaties nodig
