The HumiSys PPM is a new version of HumiSys HF (high flow) RH generator that was developed for fast and trace moisture generation in the low ppm to thousands of ppm region. The triple mass flow controller design combined with added cooling capabilities (Peltier module) allows operation in the low RH region that is normally too difficult to achieve using a typical divided-flow technique employing two MFC. Two MFC of low flow rates and one RH probe are used for generating the humidified stream of known RH, temperature, and flow rate. The third MFC of higher flow rate is utilized for dilution of the stream.
Design Features:
-Three mass flow controllers (MFC) – fast response
-Large range of flow range – up to 50 L/min
-Can be used as a regular RH generator or as a low RH (ppm region) RH
