SAC Particle Deposition Monitor - QSGroup

SAC Particle Deposition Monitor


  • Large 50 sqcm detection area allows for measurements in very clean environments.
  • High detection resolution with mask system allows detection of single particles.
  • Real time measurements providing event catching every minute with a resolution of one particle.
  • Counting sizing and positioning of all particles on the witness disk.
  • Fiber counting and images of all particles on the disk.
  • The borosilicate disk can be sterilized in order to measure the ratio between deposition and deposition with a bio content.
  • Smallest detectable particle is >= 5μm
  • Witness plates in exposure boxes allow data collection without instrument.
  • A large selection of reporting values is available such as i.e. PAC, PDR, Illigwert etc. Specials can be done.
  • Use cases are automotive industry cleanliness during assembly
  • Semiconductor industry monitors deposition during the assembly of machines.
  • Space industry safeguards the contamination budget of optical instruments.
  • There are several jobs that can be carried out with the use of a PDM system. Even the quality of a wipe can be found in combination with the specific dust you have.
