  • low-level C14 radiation source
  • uses beta-ray attenuation and a filter tape system
  • inlet is heated but filter is at ambient (station) temperature
  • humidity problems in early units caused higher readings in the summer
  • ‘smart heater’ is turned on by a relative humidity sensor
  • hourly average output
grimm 180 multi channel aerosol spectrometer
Grimm 180 Multi-channel Aerosol Spectrometer

Simultaneous measurement of PM1.0, PM2.5 and PM10

Particle counts by size (31 channels) and mass determination

using algorithms

No size cut on inlet – moisture control using Nafion dryer

Truly continuous (real-time)

  • Truly continuous (real-time)
  • Combination nephelometer & beta-ray attenuation
  • Light scattering photometer is continuously calibrated by beta attenuation mass sensor
  • Intelligent Moisture Reduction (IMR) System heating the inlet tube; threshold is set at 40%
