Special Features:

The dew point sensor in the DPL4000 performs two functions that provide increased accuracy and response time.

• Automatic Calibration – The sensor warms itself and performs an offset (zero point) correction.  This is performed automatically at start up and after every 45 minutes of continuous use.

• Sensor Purge – This function evaporates all excess moisture molecules from the sensor to significantly increase the response time when the sensor goes from a wet condition to a dry condition.  This is performed automatically at startup and after every 24 hours of continuous use.  A Sensor Purge will also be initiated automatically when the sensor detects a large wet-to-dry environmental change.
