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.
ZEGAZ Instruments DewPoint Duo™ water and hydrocarbon dewpoint analyzer is the most advanced dewpoint measurement system available, capable of measuring both dewpoints simultaneously.
It has an accuracy of ±0.5⁰C (±0.9 ⁰ F), distinguishes between hydrocarbon and water dewpoints and provides highly accurate, measurements. It is based on CEIRS™ (ChilledEvanescent Infrared Spectroscopy), a patented method.
ZEGAZ Instruments products are the only analyzers in the world that use CEIRS™, a spectroscopic approach that determines the dewpoint, while unambiguously determining whether it was water or hydrocarbon dewpoint. It has an accuracy of ±0.5⁰C (±0.9 ⁰ F), distinguishes between hydrocarbon and water dewpoints and provides highly accurate, measurements.
It is based on CEIRS™ (ChilledEvanescent Infrared Spectroscopy), a patented method.
