The High Flow Sampling System (HFSS) 140-HFSS is an accessory designed to be used with QCM-MOUDI™ Impactor 140 when sampling ambient air at hot and humid environmental conditions.
The High Flow Sampling System 140-HFSS can reduce relative humidity of the sample air at a flow rate of 10 L/min from as high as ~100% at 40 °C to below 80% at normal room temperature (i.e. 25°C), avoiding water condensation in the sampling line.
