The CONG Prima-10 dew point analyzer is an automatic on-line hygrometer. It comprises two components, the online Dew Point Transducer unit, which incorporates Vympel’s laser-based interferometric automatic dew point registration technology, and a supporting secondary electronics unit. This analyzer can measure the water dew point and hydrocarbon condensation temperature or both alternately, with unsurpassed accuracy. An unbeatable choice for on-site installation, the CONG Prima-10 is designed to measure the dew point of water even in the presence of glycols, methanol, and higher hydrocarbons. Alternatively, this high-precision instrument is also superior laboratory hygrometer, fine-tunable to an accuracy of ±0.25 °C.
