ELPRO's new cleanroom monitoring panel meets construction specifications for clean and ultra-clean environments by providing functional audible/visual signals, compact design, and easy service.  Users immediately see the cleanroom status from both inside and outside the cleanroom, as parameter displays backlit either green (OK), yellow (warning), or red (alarm). The panel also houses a local audible alarm for added security.  Integrated parameters include temperature, relative humidity, pressure differential, and 4..20mA signals. The front of the panel includes an exchangeable sensor for temperature / relaltive humidity and access connections for calibration, making servicing easier and ultimately lowering maintenance costs.
