Sampling lines carrying gas to the sensor must be heated and insulated when the dew point of the gas is above the sample line's ambient temperature. The simplest way to achieve this is to use this Heated Sample Line which is specifically designed to be compatible with the Panametrics Optica chilled mirror hygrometer. This heated line is 15ft. (4.6 meters) long. Power supply is 115 VAC, 60Hz.
