Environmental Monitoring Systems (EMS)

When maintaining environmental conditions is critical to production, facility owners often utilize environmental monitoring systems (EMS) to record and verify conditions, comply with requirements standards, and keep HVAC systems in check. EMS are used in production processes, clean rooms, laboratories and research facilities to monitor, alarm, and record temperature, humidity, air pressure and particle measurements.


In years past, it was common practice to qualify an entire building automation system (BAS), a time-consuming and expensive undertaking, in order to meet GMP, GLP or FDA environmental condition requirements. Environmental monitoring systems were developed to meet these requirements without unnecessary overkill. Environmental monitoring systems and building automation systems operate independent of each other, though both systems can use the same sensors to obtain readings. Measurements are recorded and saved on a separate server and cannot be manipulated.


High-quality instruments and proper calibration using NIST-certified equipment is crucial to environmental monitoring system accuracy. Of course, detailed commissioning, sequence testing and air and water balancing on the BAS side is just as important to deliver optimal environmental conditions. In order to have a good EMS, you must have a good BAS.


MSC | Mechanical Service Corp. specializes in building automation and controls systems for commercial, industrial and institutional facilities, and we are highly experienced in environmental monitoring systems as well. We provide selection, calibration, installation and diagnostics for any EMS system.
