AeroTrak High Pressure Diffusers


Enables measurement of particulate contamination in high-pressure compressed gas systems for cleanroom particle counters.

Product Details

The TSI AeroTrak® High Pressure Diffuser (HPD) Model 7950, Model 7955 and Model 7960 accessories allow the TSI AeroTrak Cleanroom Particle Counters to measure particulate contamination in high-pressure compressed gas systems. As particle counters cannot sample high pressure gas, they require HPD accessories to reduce the pressure of compressed gases to assess the cleanliness level of compressed gas systems.
