The High Dilution CPC™ (CPC-HD™) is a condensation particle counter (CPC) with an integral, multi-stage, variable-ratio diluter for high accuracy single particle counting at high concentrations. Traditional CPCs cannot measure aerosol above 1x105 per cc in concentration by single particle counting due to coincidence counting errors and must use the less accurate photometric mode for the measurement.

• High accuracy Dual Reservoir, Advanced Technology CPC
• Continuously re-circulating, high accuracy aerosol dilutor for up to 125 to 1 in dilution per
  stage in a single, or a two-stage system
• High accuracy, single particle counting up to 1.25x106 per cc with a single diluter stage and
  up to 1.5x108 per cc with a two-stage diluter
• User selectable, lower detection limit in CPC operation from 5nm to 20nm
• High accuracy flow control with pulse-width modulated control of pump and blower speeds
• Continuous temperature, pressure and relative humidity measurement
• Automatic temperature and pressure compensation
• User-friendly, single-PCB computer with user friendly, recipe control for system setup and
  operation

• High accuracy aerosol measurement by single particle counting for aerosol research and
  laboratory and environmental measurement
• Characterize exhaust particulate emission from Diesel and spark-ignition engines and other
  combustion sources
• Measure atmospheric condensation particles to detect nucleation events
• Indoor air quality research
• Industrial hygiene studies including the measurement of welding fumes at high concentrations

Applied Physics, Inc. can repair a variety of CPC products from PMS and TSI. We will evaluate your CPC at a standard labor cost, determine what problems the CPC has, send you a quote for repair, and on your approval with purchase order, we will order parts as required, repair, test and calibrate your CPC(s). Below are various images of Condensation Particle Counters we can repair for your Maintenance Engineers.
