IMR - Model DCEM 2100 - CEMS - Dual Pass Opacity / Dust Monitor - Brochure

The DCEM2100 provides a continuous measurement of opacity or dust concentration in flue gases by continuously measuring the transmissivity of visible light across a process duct or stack. Its dual-pass optical arrangement is based on twin transmissometers measuring in opposing directions through the same section of the gas stream, providing not only an accurate average of the dust loading, but also providing a unique dynamic assessment of any misalignment errors due to stack movement. The DCEM2100 is a dual-pass transmissometer configured for the continuous measurement of opacity and dust in flue gases.
