EMS520 EPA Compliant Opacity and Dust Monitor

EMS Manufactures high quality EPA compliant Opacity and Dust Monitors

The EMS520 Opacity & Dust  Monitor meets or exceeds EPA regulation 40 CFR 60 appendix B, PS-1 and ASTM D 6216.  It is the definition of reliability, featuring an intuitive 5.7″ color touch screen user interface and long life EPA compliant LED light source.

EMS520 Data Sheet

The EMS520 utilizes dual beam measurement and the highest quality optics to assure accuracy and dependability. It features an electronically modulated long life EPA compliant LED light source which is immune to ambient light and carries a lifetime replacement warranty.

Our 5.7″ color touch screen user interface includes five numeric display screens as well as three trend displays.  This control unit performs all vital computations with resolution of 0.1% opacity and provides outputs correlated to stack exit opacity.

Designed to mimic the ease of use of a smartphone, this intuitively designed controller gives the user many options for customization.  Some of these options and features include;

  • Output definition selection
  • Password protected user and technician settings
  • Real-time diagnostics (sensor simulation, color coded relay and fault status)
  • Selectable auto-cal frequency
  • Manual calibration initiation
  • Selectable early warning and delay values
  • Window dust alarm
  • SD card data backup (opacity values, alarm history and program)

The sensor and reflector are housed in NEMA 4 watertight enclosures and are designed to swing away from air plenum for easy installation and service. Adjustments in alignment are accomplished by utilizing our “Through the Lens” system which includes a 3 point adjustment that is integral to the air plenum.

SSM in BoxThe  smart service module, located in the stainless steel weather cover, is used to pass signals to and from the transceiver and control unit. It initiates maintenance zero and span cycles as well as displays important information at the mounting location. The service module is useful for trouble shooting and eliminates the necessity for a second technician
