The series of bipolar corona discharge units offers a reliable method for neutralizing a charged aerosol. This aerosol can consist of both drops, as well as solid particles. The CD system has been used successfully for many years in filter testing. This type of discharge of charged aerosols even has its own standards prescribed, e.g. ISO 11155-1. No operating licence is necessary for this type of ionization. The generation of ions with a positive and negative high voltage is purely electric and can therefore be switched off at any time. This discharge unit is also characterized by its simple operation. Two models are available for your measurement tasks that differ in their mixed flow.
