Condumax II On-Line is a fully self-contained hydrocarbon dew point analyzer, using the proven "Dark Spot" hydrocarbon dew point measurement principle from the highly successful Condumax instrument. Combining a hydrocarbon dew point cell and water dew point measurement in the same compact and lightweight EExd enclosure, Condumax II On-Line requires nothing more than mains power to operate.
