Advantages & Use

  • Measurement according to ISO 29463-5 and 29463-3, as well as ISO 16890 (ISO ePM1; ISO ePM2.5; ISO ePM10) in one channel possible (depending on model)
  • Dual channels on request
  • Particularly wide range of application for separation efficiency measurement from 0.02 to 40 ยตm
  • Measurement of dust holding capacity possibleย 
  • Customization of filter adapters, flow channel and measuring ranges possible for optimal test performance
  • Modular compact design for small filter elements, low space requirement

Advantages & Use

  • Real-time determination of the fraction separation efficiency above 20 nm
  • Measuring time for determining the fraction separation efficiency is halved by measuring the particle concentration in the raw and clean gas.
  • Combining two UF-CPC versions, the UF-CPC for the highest concentrations, up to 2,000,000 particles/cm3ย (single count mode) in the raw gas and the UF-CPC 50 for top counting rates at low concentrations in the clean gas, corresponds to a dilution factor of 1:200.
  • Internationally comparable measurement results in accordance with DIN EN 1822-3 and ISO 29463-3
  • Easy to operate
  • Cleaning can be performed independently by the customer
  • Short set-up times, fast throughput times
