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. It 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.


ZEGAZ Instruments’ Products

DewPort™ Portable Water and Hydrocarbon Dewpoint Analyzer  



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


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.



HCD5000™ Hydrocarbon Dewpoint Analyzer

HCD5000™ is designed for the measurement of hydrocarbon dewpoint of a natural gas stream at pressures up to 1500psi. HCD5000™ is the successor to the groundbreaking HCD4000™ and HCD4500™ models.
