The Roscid Technologies 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 Roscid 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 -80C to 15C 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.
