Self-contained Hydrocarbon Dew-point Analyzer - CondumaxII
Condumax II 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 requires nothing more than mains power to operate. Condumax II provides a continuous local indication of key measurements in addition to analogue and digital outputs for remote monitoring.
