sentences:  In this way, the device is able to distinguish between water condensation and other types of condensates, such as, for example, hydrocarbons when the gaseous media is natural gas.One advantage of this method is its relative immunity to contaminants thanks to the inert natural of the transparent material.Similar to a true chilled-mirror device, this type of analyser can accurately measure the condensation temperature of potential liquids in a gaseuos medium, but is not capable of measuring the actual water dew point as this requires the accurate measurement of the evaporation temperature as well.
