Ei4200 Dew Point Monitor

Online Detection and Measurement

Available for Download

The Ei4200 Dew Point Monitor (DPM) detects condensation and measures the dew point of acid and other condensables in challenging industrial conditions. The direct measurement of the process gas dew point provides plant operators with information that would otherwise be an impercise multi-variable equilibrium calculation. Whether used as an alarm to instantly detect leaks in sulfuric acid plants or to measure dew points in other industrial applications, the Ei4200 DPM technology removes the guesswork and provides real-time feedback.
