LSA - Model 1405-D TEOM -Continuous Dichotomous Ambient Particulate Monitor

Two particulate matter parameters simultaneously: PM2.5, PM10 or PM coarse . 

Simultaneously measure PM Fine (PM-2.5), PM Coarse, and PM-10 mass concentrations with the Thermo Scientific™ TEOM™ 1405-D Continuous Ambient Particulate Monitor. This monitor utilizes a tapered element oscillating microbalance (TEOM) for measurements with excellent short-term precision.Consisting of a TEOM mass sensor and control unit in a network ready configuration, the TEOM 1405-D distinguishes itself from other PM measurement methods by utilizing a direct mass measurement that is not subject to measurement uncertainties found in other surrogate technologies. It provides a self-referencing, NIST traceable direct mass measurement.
