HPD III High Pressure Diffuser Aerosol Monitoring Accessory BENEFITS • Measures gases from 5 to 100 psi (range dependent on model) • No external flow meters needed • Low contamination, < 5% of ISO Class 5 cleanliness • Economical monitoring of pressurized gases with atmospheric pressure particle counters • Can be used with Clean Dry Air (CDA), argon, nitrogen, carbon dioxide or other non-toxic inert gases • Seven different versions for 0.1 CFM, 1.0 CFM, 50 LPM, and 100 LPM flow rates F E AT U R E S High Pressure Diffusers (HPDs) have been developed to address the challenge of sampling pressures of 5 – 100 psi, and the possible damage that can result from connecting pressurized air or gas to a particle counter. HPDs reduce the pressure of the gas to near atmospheric pressure by allowing some of the gas to diffuse out of the system, allowing the particle counter’s flow-metering system to function as designed. The HPD III Aerosol Monitoring Accessory is compatible with nontoxic, non-flammable gases such as Clean Dry Air (CDA), argon, nitrogen and carbon dioxide. The higher pressure gases are reduced to a level acceptable to particle counters designed to operate at atmospheric pressure. • No moving parts to wear • Connects via male 4-VCR fitting • Exhaust filter prevents possible room contamination • Mounting clamps supplied • Stainless steel construction A P P L I C AT I O N S • Nano-ID® NPC10 nanoparticle counter • Lasair® III particle counter models 310B, 310C, 350C, and 5100 • Airnet® II particle sensor models 301, 501, 510, and 510XR • IsoAir® 310P particle counter
