Differential Pressure Monitor

Our easy to install wireless differential pressure monitoring system can detect -50 to +50 Pascal. The differential pressure monitor records and transmits the data via a wireless bridge for immediate online access. Aretas' differential pressure sensor measures the difference in pressure between two environments. Rooms or facilities that need to have positive or negative pressure can be monitored from the outside of the room.

The differential pressure monitoring device comes standard with temperature and relative humidity and can be combined with other sensors including CO, CO2, NO2, VOC, even fine particulates to provide you with accurate information about your indoor environments.

What is differential pressure?
The difference in air pressure between two spaces, potentially leading, in the case of a pressure difference, to the migration of contaminants from one space to another.

Why monitor differential pressure?
Differential pressure is used in many industrial manufacturing and healthcare applications. Operating Rooms, Isolation Rooms and Clean Rooms require accurate differential pressure monitoring to ensure they meet specific needs. As an example clean rooms are setup to eliminate fine particulate matter and other contaminates such as microorganisms or toxins. To provide a controlled physical environment monitoring for temperature, humidity and pressure are required though controlling these three parameters is often not an easy task. Our solutions provide you with all three sensors and allow you to set alert levels that meet your specific needs.

The Aretas monitoring system allows you to monitor one or more rooms and facilities from one online analytics platform 24/7 worldwide. Find out more by calling us today!
