Key Features

  • Adjustable mechanical layout
  • The use of moving filter tape allows continuous measurement from 3 months to 1 year without the filter replacement (depending on the movement mode)
  • Continuous or periodical movement of the filter tape
  • Background compensation in real time
  • Radon/Thoron compensation
  • Adjustable alarm levels for alpha and beta channels
  • Easy maintenance
  • Compliant with IEC 60761, IEC 61172 and IEC 61578
  • Various communications interfaces


The CPM-300 monitor is designed to continuously measure the alpha and beta particulates concentration in the air. The air can be sampled directly from working environments, ventilation systems or surrounding environments.

The CPM-300 monitor consists of three parts mounted on a carrier frame:

  • Display Unit
  • Continuous Particulate Detector CPD-14
  • Vacuum Pump VP-30
