The Thermo Scientific TEOM 1405-F is a Continuous Ambient Particulate Monitor with a Filter Dynamic Measurements System. The one-piece system provides total mass measurements by accounting for volatile and non-volatile PM fractions, making it the worldwide standard.
The Thermo Scientific TEOM 1405-F Continuous Ambient Particulate Monitor with FDMS measures PM-10 and PM-2.5 mass concentration as it exists in the ambient air. The TEOM 1405-F Continuous Ambient Particulate Monitor with FDMS system is composed of a Filter Dynamics Measurement System (FDMS) and a TEOM mass sensor housed in a single cabinet, network-ready configuration that includes the control system with touch screen user interface.
The TEOM 1405-F Continuous Ambient Particulate Monitor with FDMS is designed to provide representative short and long term reading of the ambient PM concentration, even in the presence of volatile materials. Conventional PM monitoring approaches do not account for the rapid loss that can occure with collection on a filter while sampleing ambient PM. The TEOM 1405-F Continuous Ambient Particulate Monitor with FDMS overcomes this challenge by automatically generating mass concentration measurements that account for both non-volatile and volatile PM components.
The system's default data output consists of a running 1-hour and 24-hour average mass concentration updated every 6 minutes and on the hour respectively. The monitor computes a 1-hour FDMS base and reference mass concentrations updated every 6 minutes. User can select additional averaging times from 30 minutes to 23 hours.
The TEOM 1405-F Continuous Ambient Particulate Monitor with FDMS provides a self-referencing, NIST-traceable true mass measurement using Thermo Scientific's proven high reliability TEOM technology.
