The TEOM 1405D Dichotomous Continuous Ambient Particulate Monitoring simultaneously measures PM-10, PM-2.5 and PM-Coarse (PM10-2.5) mass concentration. The 1405D system is comprised of two TEOM mass sensors housed in a single cabinet.
The TEOM 1405D Dichotomous Continuous Ambient Particulate Monitoring is the replacement for the successful 1400ab which is the choice of particulate monitoring networks worldwide. The TEOM 1405 Continuous Ambient Particulate Monitoring has become the de facto standard for particulate monitoring in areas such as Canada, Hong Kong, the United Kingdom and France due to its high data quality and reliability.
This particulate monitor provides a self-referencing, NIST-traceable true mass measurement using Thermo Scientific's proven high reliability TEOM technology when particulate monitoring. The TEOM 1405D differentiates itself from other PM measurement methods by utilising a direct mass measurement that is not subject to measurement uncertainities found in surrogate techniques such as beta attenuation, light scattering and pressure drop.
With touch screen user interface and Activol flow control the TEOM 1405D Dichotomous Continuous Particulate Monitoring provides unmatched short-term precision and resolution when particulate monitoring.
