QVA - Model HHAD - Aerosol Diluters for Handheld Particle Counters - Brochure

Milholland & Associates NIST traceable aerosol dilutors have been refined and proven in over 20 years of actual cleanroom testing. They are designed specifically for low concentrations of Poly Alpha Olefin (PAO) or Polystyrene (PSL) microsphere aerosols and use capillary flow as the principle of operation. These units are very durable and drift free. They do not rely on electronics, mass flow meters, transducers, or orifices.
