Introduction PMS HPD III High Pressure Diffuser
The HPD III Aerosol Monitoring Accessory (PMS HPD III) is compatible with non-toxic, non-flammable gases such as Clean Dry Air (CDA), Argon, Nitrogen and Carbon dioxide.
Typically Ships within 24 hours*
Sampling gases at pressures greater than sea level, such as 25 – 100 psi, is challenging for particle counters. Connecting pressurized air or gas to a particle counter can defeat its flowmetering system and possibly damage the instrument.
High Pressure Diffusers (HPDs) have been developed to address particle counting in compressed gas. HPDs reduce the pressure of the gas to about atmospheric pressure by allowing some of the air/gas to diffuse out of the system and allow the Lasair III particle counter’s flow-metering system to function as designed.
Features PMS HPD III
- No moving parts to wear
- Connects vis male 4-VCR fitting
- Exhaust filer prevents possible room contamination
- Mounting clamps supplied
- Stainless steel construction
Benefits
- Measures gases from 25 to 100 psi (60 to 100 psi for 100LPM)
- No external flow meters needed
- Low contamination, < 5% of ISO Class I or II cleanliness
- Economical monitoring of pressurized gases with atmospheric pressure particle counters
- Can be used with Clean Dry Air, Argton, Nitrogen, or other non-toxic inert gases
- Four different versions for 0.1 CFM, 1.0 CFM, 50 LPM, and 100 LPM flow rates
