The dew point generator, model PPMG101, is a precision moisture/humidity generator able to create a wide range of moisture levels. It can be used as a standalone verification unit or used in synchrony with an NIST traceable chilled mirror hygrometer to create a transfer standard calibration system for metrology labs, R & D and field calibrations.
The PPMG101 dew point generator accepts a flow of dry gas, typically Nitrogen. Using a precise mixing control system moisture is added to the gas in order to produce an output gas flow with a target moisture level. For many humidity control applications, the PPMG101 may be used as a stand-alone moisture generator. When paired with a chilled mirror hygrometer such as the Dewtran, it can create a calibration lab grade moisture/humidity standard. Using the two instruments together, the PPMG101 dew point generator can create the desired moisture level. The dew point hygrometer is a primary standard measurement standard which can provide the precise moisture level.
The PPMG101 double dilution system offers a wide mixing ratio range of 50,000 to 1 (.5ppm to 25000 ppm) allowing a dew point/frost point range of -80°C to 15°C to be achieved. Regardless of the mixing flow adjustments, the flow output is constant, condensation and water backup issues removed because of the elevated saturation pressure and the total flow control meter.
