DESCRIPTIONAPPLICATIONS

• Hospital isolation rooms

• Pharmaceutical facilities

• Dental ofces

• School nurse ofces

The Series RSME Room Status Monitor is designed for low differential pressure applications that require stringent

pressure monitoring and alarming. It can be congured to monitor positive or negative pressure in clean rooms, hospital isolation rooms, laboratories, and vivariums. The RSME is a complete system with a touchscreen graphical user interface which enables access to pressure, humidity, temperature, air change, security, door status, calibration, and alarm setup. The graphical display color changes allows a clear determination of when the parameters are operating within the acceptable range (green), caution range (yellow), or have gone outside the acceptable operating range (red). The RSME room status monitor comes standard with BACnet MS/TP and Modbus® RTU communications.
