DEMC 2000

Differential electrical mobility classifier from 8 – 1400 nm

The DEMC size classifier (as defined in ISO 15900) selects aerosol particles based on their electrical mobility and directs them to the outlet. It is also often referred to as a DMA.

The Palas® DEMC universally connects to CPCs and aerosol electrometers from other manufacturers. Several counters are already supported. We will also integrate your counter into the software upon request.
