Input Required: Dry gas less than 115 PPM* (-40ºC dewpoint) 13 SCFH (6 Litres/min.) 30-100 psig

* - Even dryer gas is preferred as the dryness of the inlet gas limits the lowest dewpoint that can be generated.

Accessories:

Model 1500 or Hygro M2 with 1311DR or 1211H Sensor. The setup procedure for the DPG300 allows you to compute the moisture content of your inlet gas utilizing the generator and a precision chilled mirror hygrometer. This dry gas calculation can be made even if the dry gas moisture content is below the range of the dewpoint sensor employed.

Five Chilled Mirrors are sampling air from a DPG-300 Dew/Frost point generator.

The units read -25.0, -25.1,
-25.1, -25.0 and -25.0°C Frost point respectively; A spread of 0.1°C Frost point.

The D2 Sensors are over 5 years old. The units were sent into our facility for annual calibration service.
