HPD II High Pressure Diffuser Lasair® III 110 and Lasair II 110 Accessory Particle counter accessory that allows direct sampling of pressurized air, nitrogen, and inert gases BENEFITS The HPD II reduces the pressure of dry, inert, non-toxic, non‑flammable gases, such as Clean Dry Air (CDA), nitrogen and argon to a level acceptable for the Lasair III 110 and Lasair II 110 aerosol particle counters, which are designed to operate at atmospheric pressure. • Two models to reduce high-pressure gas between 40 – 100 psi or 75 - 150 psi to about atmospheric pressure • Use in conjunction with compatible particle counter to measure particles as small as 0.1 µm in CDA, nitrogen or argon • Allows users to efficiently monitor pressurized gases with standard aerosol particle counters F E AT U R E S • Specifically designed for use with the Lasair III 110 and Lasair II 110 particle counters • Simple connections for gas inlet/outlet • Filtration of any excess gas • Particle counter can remain on, even when
