natural gas analyzer

ZEGAZ Instruments | Hydrocarbon and Water Dewpoint Measurement | Natural Gas Analyzers

ZEGAZ Instruments’ water and hydrocarbon dewpoint analyzers are the most advanced dewpoint measurement systems available. They are based on breakthrough CEIRS™ infrared technology to accurately and unambiguously determine the dewpoint of hydrocarbon gas streams at pressures up to 1500psi. These systems can distinguish between hydrocarbon dewpoints and water condensation.

ZEGAZ Instruments’ analyzers do not need field calibration and will retain their factory calibration under normal operating conditions. They also does not need any field adjustments as the measurements are done based on a very accurate detection of the condensation process and the nature of the condensate.


DewPort™ Portable Water and Hydrocarbon Dewpoint Analyzer

DewPort™ Datasheet

DewPort™ is the World’s only truly portable, automated, water and hydrocarbon dewpoint measurement system.  It uses the patented CEIRS™ technology to accurately and simultaneously provide both water dewpoint measurements and hydrocarbon dewpoing measurements, while distinguishing between the two.  Weighing at only 15 lbs (7 Kg) and using an average of less than 30W, it offers unprecedented reliability and maintenance-free operation.  This product is the perfect replacement for the cumbersome-to-use manual chilled-mirrors.

 DEWPOINT DUO™ On-Line Water and Hydrocarbon Dewpoint Analyzer

DewPoint Duo™ Datasheet

Now for the first time, incorporated within a single instrument, DEWPOINT DUO™ allows simultaneous measurement of water and hydrocarbon dewpoints.  This is the most advanced instrument of its kind on the market and is the culmination of several years of research and development by ZEGAZ Instruments. Certified for use in hazardous locations.  DEWPOINT DUO™ is deployed on some of the largest pipelines and gas refineries in the world.  DEWPOINT DUO™ carries CSA (Class I, Div.1) and ATEX/IECEX (II 2 G Ex db IIB+H2 T6 Gb) hazardous location certifications.


 HCD5000™ Hydrocarbon Dewpoint Analyzer

HCD5000™ Datasheet

HCD5000™ is designed for the measurement of hydrocarbon dewpoint of a natural gas stream at pressures up to 2000 psi.  It is based on the groundbreaking CEIRS™(Chilled-Mirror Evanescent IR Spectroscopy).  HCD5000™ is bay far the most advanced analyzer of its kind offering unambiguous and reliable measurements.  HCD5000™ carries CSA (Class I, Div.1) and ATEX/IECEX (II 2 G Ex db IIB+H2 T6 Gb) hazardous location certifications.

 WDP5000™ Water Dewpoint Analyzer

WDP5000™ Datasheet

WDP5000™ is the only analyzer designed for the first-principle detection of moisture dewpoint in natural gas.  Most other analyzers measure moisture content at low pressure and then estimate water dewpoint at a higher pressure. WDP5000™ uses a novel implementation of chilled-mirror technology to accurately and unambiguously detect the water dewpoint at the supplied pressure.  It can handle pressures up to 2000 psig (137 barg) eliminating the need to reduce the pressure, thus avoiding errors associated with pressure regulation.  WDP5000™ carries CSA (Class I, Div.1) and ATEX/IECEX (II 2 G Ex db IIB+H2 T6 Gb) hazardous location certifications.
