The Model 1304 Opacity Monitor
	The double pass 1304 Opacity monitor meets the 40 cfr 60, appx B, Specifications 1 (February 6, 2001) and ASTM-D 6216-98
	High Performance Opacity Monitoring System with Double-Pass Transmissometer does not have to mean complicated -The Model 1304 uses field proven and time tested optics and circuitry that is simple yet accurate. Each monitor and all its components are of the highest quality, pre-tested at the factory to your site specifications. The simple to follow instructions will have your monitor ready for service in hours after mechanical and electrical installation have been completed. EMS has taken the approach to design equipment with accuracy, maintenance and serviceability as the most important features. The EMS 1304 Opacity monitor is designed with state of the art modular packaging with serviceability in mind. A built-in TTL (through-the-lens) alignment system. The alignment target can be viewed through a window on the transceiver. Adjustments to changes in alignment are provide by a 3 point alignment system which is integral to the air plenum. This insures optimum reliability while enabling the system to be easily serviced and maintained in the field by plant service personnel.
Large numeric and letter display show legends (programmable in English as well as other languages) for the values of user defined variables. Dual five inch tall bargraphs are used for instantaneous and average opacity. A third bargraph is dedicated to window dirt accumulation. Tactile feedback membrane push buttons allow operator interface through clearly defined legends with minimum number of keystrokes. The control unit performs all vital computations with resolution of 0.1% opacity (1mg/M3). EMS Model 1304 can provide an output correlated to either stack exit opacity or mg/m3 . State of the art circuitry eliminates calibration problems due to component aging, temperature and line variations and light source aging. Outputs for recording or control are in a 4-20mA format with selectable ranges and averaging times. Display and outputs of alarms for opacity and fault diagnostics are also provided. User Friendly
	The service module is used to pass signals to and from the transceiver and control unit, display opacity via digital meter, initiate maintenance zero and span cycles and insertion of external current meter in the transceiver to control unit 4-20mA loop. The service module is very useful for trouble shooting or during EPA audits as the correlated opacity can be displayed on the DPM. This feature eliminates the necessity for a second person and sometimes difficult communication between the control unit and the sensor locations.
