 Our COSA XENTAUR™ Portable XPDM™ Dew Point Meter is a battery operated, hand-held, hygrometer, designed for applications where quick and accurate dew point measurements have to be made. 

Pricing for US, LATAM, and Canada Only.

The Portable XPDM Dew Point Meter fast and precise and ideal for spot checking moisture. With the XPDM, accurate spot-checks of moisture in gases can be made faster and easier than ever, over the range of -148°F to +68°F (-100°C to +20°C) dew point.

The XPDM dew point meter utilizes HTF™ 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.

SpanCheck™ Without Reference Standards
Our HTF™ high capacitance sensors have a very low residual capacitance when dry and saturate at a predesigned level of humidity above +20ºC (+68ºF). This allows a SpanCheck™ of the sensor by exposing the sensor to a saturated environment for one minute and adjusting the instrument to its upper range limit. It is preferred that the customer use a known gas to determine the saturated environment.
