Portable Dewpoint Meter XPDM

The Xentaur dew point meter, XPDM utilitzes HTFTM aluminum oxide sensors which adsorb water molecules much faster than they desorb water molecules. It is therefore an advantage, if at the beginning of the measurement the dew point sensor is dryer than the gas sample to be measured. The XPDM dew point meter keeps the sensor in dry storage until the measurement is taken. The sensor slides directly from the dry storage into the sample cell, without ever coming in contact with ambient air. After the measurement is completed, the sensor slides back into the dry storage, where it is dried down for the next sample.
