What is a room pressure monitor? A room pressure monitor is a device that monitors and measures the pressure of a given space in reference to another space. This value is called "differential pressure."

Where are room pressure monitors used? Room pressure monitors are used in "critical spaces" where contamination must be avoided. Critical spaces include hospital rooms, isolation rooms, operating rooms, cleanrooms, pharmaceutical manufacturing areas, vivariums, and data centers.

What is the difference between a room pressure monitor and a room environmental monitor? Environmental monitors can measure additional room parameters beyond pressure such as humidity, temperature, particle count, velocity, door status, occupancy, and more. Room pressure monitors typically only measure differential pressure.

Why would I need an environmental room monitor? Some critical spaces such as data centers require monitoring more than just pressure to keep equipment running at peak performance. Pharmaceutical plants and other involved manufacturing facilities typically need to control the humidity, temperature, and particle counts of their spaces. Finally, a growing body of research is showing that hospitals can reduce infections by monitoring additional room parameters beyond just differential pressure.

Are there solutions for less critical spaces such as sterile storage areas? Yes, room pressure indicators can provide the ideal solution for simple differential pressure applications.

What is recommended for hospital room pressure monitoring? The top solutions for hospital room pressure monitors are Setra's FLEX and SRPM. Both are used extensively in hospitals across the world and are considered the standard when reliability and accuracy are critical.
