1405-F TEOM Continuous Ambient Air Monitor


PM1, PM2.5, PM10 or TSP


Take continuous direct measurements of PM-10, PM-2.5, and PM-1 particulates using the Thermo Scientific™ 1405-F TEOM™ Continuous Ambient Air Monitor. This monitor utilizes a tapered element oscillating microbalance (TEOM) and Filter Dynamics Measurement System (FDMS) to provide measurements with excellent short-term precision and account for volatile and nonvolatile PM fractions.The 1405-F monitor provides a selfreferencing, NIST-traceable true mass measurement using our proprietary TEOM technology. It complies with U.S. EPA PM-2.5 Equivalent Monitor EQPM-0609-181.


  • Candidate for U.S. EPA and TÜV Equivalency
  • Accounts for volatile and non-volatile PM fractions
  • Combines control unit, mass sensor and FDMS into a single integrated unit
  • Embedded FTP server, Ethernet, USB, RS-232 and RS485 communications
  • Activol flow control
  • Real-time Mass Concentration Average: One hour rolling average updated every six minutes
  • Long-Term Averaging: 1, 8, 24 hr.
