Condensation Particle Counter 3007

Request A Quote Accessories

Mobile instruments like this Condensation Particle Counter (CPC) are designed to measure particle concentrations in the field. This Handheld CPC can be used to assess concentrations or emissions in larger buildings or areas, such as schools, workplaces, hospitals and other sensitive environments. With performance comparable to scientific instrumentation, the results captured with this CPC are very reliable.

Product Details

The handheld CPC model 3007 offers one-button operation and an easy-to-exchange wick. It is designed to take isopropyl alcohol (IPA) as its working fluid, so it is easy to keep the necessary consumables on-hand. At a weight of 1.7 kg (3.8 lbs), it's perfect for mobile particle number measurements.

Features and Benefits

  • Particle size range of 0.01 to >1.0 µm
  • Concentration range of 0 to 100,000 particles/cm 3
  • Battery-powered operation
  • Programmable data-logging capabilities


  • Indoor air quality measurements
  • Mobile aerosol studies
  • Inhalation and exposure studies
  • Health effects studies

  • Can the CPC be operated with different carrier gases?
    Yes, but only inert gases.
  • Is the counting efficiency for each CPC determined individually?
    No. The CPC efficiency curve has been determined by testing a statistically valid number of CPCs and averaging the results to obtain the curve published in the product literature. Variation between units is very small. 
  • What is the final droplet size after growth by condensation?
    This question has been investigated, theoretically, by Ahn and Liu (1990). For the initial particle diameters of 5 and 20 nm, the computation results show a final droplet size of 11.3 and 12.3 micrometers, respectively (Ahn and Liu, 1990). Similar experimental results have also been determined.
