PreHumidifier Model 3110


The Brechtel Manufacturing Pre-Humidifier is designed to bring a particle sample flow to a known relative humidity. The Pre-Humidifier can be implemented as a component of a suite of instruments, in particular the Model 3100 HTDMA, to explore the humidity dependence of particle size, efflorescence, deliquescence, and other properties.
