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.
