1405-DF TEOM Continuous Dichotomous Ambient Air Monitor

Measure

Two  particulate matter parameters simultaneously: PM1, PM2.5, PM10 or TSP

Description

Take continuous direct mass measurements of particulates with excellent short-term precision using the Thermo Scientific™ 1405-DF TEOM™ Continuous Dichotomous Ambient Air Monitor. This monitor simultaneously measures PM-10, PM-2.5 and PM-Coarse mass concentration as it exists in the ambient air.This monitor utilizes two tapered element oscillating microbalances (TEOM) and two Filter Dynamics Measurement Systems (FDMS), which account for volatile and nonvolatile PM fractions. It complies with U.S. EPA PM-2.5 , PM-10-2.5,

PM-10 Equivalent Monitor (EQPM-0609-182, EQPM-0822-207, (EQPM-0822-208)
