The TEOM Monitor, Series 1400ab, measures PM-10 or PM-2.5 mass concentrations and consists of a TEOM mass sensor and control unit in a network ready configuration. The TEOM 1400ab 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. The TEOM 1400ab provides a self-referencing, NIST traceable direct mass measurement.
