Single Pass Transmissometer The D-CEM1000/1001 Opacity Monitors consist of a visible light transmitter and receiver arrangement with digital data processing in a local display unit. The monitors can display data in either opacity, extinction or dust density in mg/m3 or normalised dust density in mg/Nm3. The D-CEM1001 possesses four analogue inputs for normalisation data; temperature, oxygen, pressure and water vapour.
