Dual Beam Transmissometer

To measure smoke density (opacity, extinction, Ringlemann) or dust density (mg/m3, mg/Nm3), the universally accepted method is to transmit a beam of light through the gas and measure the reduction in its intensity. The Forbes Marshall CODEL Model DCEM 2100 is a unique twin beam transmissometer. It combines the simplicity of measurement hardware with sophistication of measurement processing, thus providing unmatched ease. It is specially designed to provide stability of calibration and virtually maintenance-free operation for long-term continuous processes. Features: dual beam transmissometer; very low maintenance, high reliability; automatic lens contamination correction; automatic zero and span without filters; dynamic misalignment check; data displayed in % opacity, mg/m3, mg/Nm3; built-in fail safe shutter; local/remote control unit for two way communication; and normalised reporting.
