Condensation Particle Counter (CPC)

GRIMM 5410 / 5412 / 5416 / 5420

Features

  • compact and rugged standard counter
  • aerosol flow rate = 0.6 L/min ( with external pump)
  • improved detection limit with D50 = 4.0 nm for tungsten oxide particles
  • single particle counting up to 100 000 /cm³
  • improved response time with t10-t90 < 3 seconds

Specifications

  • max. concentration single count mode: 100 000 p/cm3
  • max. concentration photometric mode: 107 p/cm3
  • particle size range: 4.0 nm (D50 measured with tungsten oxide particles) to greater than 3 μm; adjustable to 7.0 nm for compliance with the standard CEN 16967 for determination of the particle number concentration of atmospheric aerosols
  • concentration accuracy: >95% for single particle counting (up to 100 000 p/cm3 at 0.6 L/min, up to 150 000 p/cm3 at 0.3 L/min)
  • 10% for optional photometric mode (up to 107 p/cm3 at specified conditions)
