Product Details
The TSI AeroTrak® High Pressure Diffuser (HPD) Model 7950, Model 7955 and Model 7960 accessories allow the TSI AeroTrak 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.
Features and Benefits
- For monitoring and testing to ISO 14644-1, ISO 8573-1 and SEMI 49.8 limits
- Reduces gas pressure of up to 120 psi (8.27 bar) to near atmospheric pressure
- Compatible with AeroTrak Portable Particle Counters , AeroTrak Handheld Particle Counters and AeroTrak 9001 Cleanroom Condensation Particle Counter (CPC)
- No manual adjustments or calibration required
- For use with Clean Dry Air (CDA), Nitrogen (N 2 ) and Argon (Ar)
- Passivated stainless steel enclosure resists cleanroom chemicals
- Exhaust HEPA filter protects HPD accessory from contamination when disconnected from compressed gas source
