在高於海平面的壓力下(如40 – 150 psi)對氣體進行採樣，對於粒子計數器來說是一個挑戰。將壓縮空氣或氣體連接到粒子計數器上，可能會破壞流量計系統，並可能損壞儀表。
高壓擴散器(HPDs)的開發著眼於解決壓縮氣體中的粒子計數問題。 HPDs通過將部分空氣/氣體向系統外擴散，將氣體壓力降至標準大氣壓，這樣Lasair III顆粒計數器的流量計量系統即可正常工作。

特點
Specifically designed for use with the Lasair III-110 particle counter
• Simple connections for gas inlet/outlet
• Filtration of any excess gas
• Particle counter can remain on, even when gas supply is off
優點
- Two models to reduce high-pressure gas between 40 – 100
psi or 75 – 150 psi to about atmospheric pressure - Use in conjunction with a Lasair III-110
particle counter to measure particles as small as 0.1 µm in
CDA (compressed dry air), nitrogen, carbon dioxide or argon - Allows users to efficiently monitor pressurized gases with
standard aerosol particle counters
