5028i Continuous Particulate Monitor

Conduct simultaneous, real-time measurement of PM10 and PM2.5 and benefit from lower maintenance requirements with the Thermo Scientific™ Model 5028i Continuous Particulate Monitor. The unit combines dual channel sampling technology and beta attenuation analysis on the proven iSeries platform to measure PM10 and PM2.5 simultaneously. The Model 5028i offers continuous, non-stepwise measurement of particulates and complies with U.S. EPA PM-10 (EQPM1102-150) and PM-2.5 (EQPM0609-183).

Key Features:

The Model 5028i Continuous Particulate Monitor combines dual channel sampling technology and beta attenuation analysis on the proven iSeries platform to measure PM10 and PM2.5 simultaneously. The Model 5028i monitor offers continuous, non-stepwise measurement of particulates. The key features of this state-of-the-art monitor are:

  • U.S. EPA Approved PM-10 (EQPM1102-150) and PM-2.5 (EQPM0609-183)
  • Federal Equivalent Method (FEM)
  • Continuous, non-stepwise measurement of PM-10 and PM-2.5 simultaneously
  • Internal backup power to reduce reliable data output time after power off/interruption
  • Filter tape-based monitor, with increased tape volume for longer unattended operation
  • New chassis design to make maintenance and service much easier
