The EMCS is a full featured Environmental Monitoring and Control System or BAS (Building Automation System. It has the ability to monitor temperature, relative humidity and differential pressure for any number of rooms or zones and also control the HVAC system if desired. Other sensor types or analytical instrumentation like TOC or Particle Counters can also be connected, and monitored. The system reads the sensors, displays the real time data in an “active tile” format and saves the data to a local database for later use in printed reports, etc.
