Water and Hydrocarbon Dewpoint Analyzer www.ZEGAZ.com 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 ±0.5 °C (±0.9 0 F), distinguishes between hydrocarbon and water dewpoints and provides highly accurate, measurements. It is based on CEIRS™ (Chilled- Evanescent 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. The CEIRS™ method uses advanced IR technology. It is immune to contaminations. It is designed for remote operation at line pressure up to 2000psi. It provides 4 analog outputs as well as 3 digital alarms, and serial communications. in ii ii min ii ii ii miKEY FEATURES DewPoint Duo™ has unprecedented accuracy and repeatability. The graph below shows the correlation between theoretical and DewPoint Duo™ measured values. • Direct, First Principle Measurement • NIST Tested • Self Cleaning • Immune to Most Contaminants • No Calculation or Model Errors • Distinguishes Between Hydrocarbon and Water • Fully Automated • Works at Line Pressure • Replacement Parts • Sensor Not Damaged by Contaminants, Slugs or Aerosols Comparison of CEIRS(TM) with GERG
