1.Tapered Element Oscillating Microbalance (TEOM)
2.Long term, unattended operation
3.Low detection limit, high accuracy
TH-2000ZD-A1 Ambient Particulate Monitor was designed to continuously measure the mass
concentration of suspended particulate matter in the atmosphere. Utilizing tapered element oscillating
microbalance, this instrument is equivalent to manual weighting method for determination of
suspended particulate matter in the atmosphere.
Operation
A known volume of air is drawn through a size-selective inlet, which can be configured to measure
PM-10, PM-2.5 or TSP, and deposited onto the Tapered Element Oscillating Microbalance (TEOM).
The combined measurement of mass and air volume are used to obtain the mass concentration
readings.
