Summary

5. DOP Efficiency Tester (Q-107)
Developed 1940s
Guaranteed Performance
Efficiency
Pressure Drop
Upstream Aerosol
Hot DOP (Dioctlyphthalate)
A Non Destructive Test

6. Q-107 Penetrometer

7. Dual Laser Efficiency Developed Late 1970’s Non Destructive Test
Counts Size & Individual Particles
Filter Pressure Drop

8. Dual Laser Efficiency
This machine has the ability to see particles that are .1 and larger (12) separate bins (Particle Sizes) that can be looked at.
This machine will use PSl’s clean challenge.

9. Leak/Scan Testing Non Destructive Test Locate Gross Leaks
Photometer or Particle Counter
Manual
Autoscan
Cleanroom Applications

10. Autoscan A Non-destructive Test to Locate Leaks
Particle Counter Method
Removes Operator Variability

11. Particle Counters Monitor Dust/Particles Determines Particle Size
Scan Test
