Michell Condumax II Hydrocarbon Dew-Point Analyzer
Brand: Michell InstrumentsThe Condumax II hydrocarbon and water dew-point analyzer provides continuous, automatic measurements of these two critical parameters of natural gas quality.
It uses the ‘Dark Spot’ direct chilled-mirror technique to measure hydrocarbon dew point with high accuracy and long-term reliability. Water dew point measurements are provided by Michell’s Ceramic Metal-Oxide Moisture Sensor.
The Condumax II is housed in a compact explosion-proof enclosure. Both indoor and outdoor sampling systems are available as standard providing comprehensive sample conditioning natural gas at up to 138 barg.
For specific applications and requirements, we offer a custom engineering design service.
Condumax II is suitable for use with natural gas containing up to 20% hydrogen with no further modification required.
