ACR Air™ Low Pressure Differential logger
Helps ensure proper air pressure control to protect people, processes, and spaces.
Monitor and log ultra-low differential pressures to assess or troubleshoot room-to-room or building envelope pressurization. This compact, wireless logger records pressure profiles over time—ideal for validating airflow direction, troubleshooting imbalances, or verifying performance in critical environments like isolation rooms, cleanrooms, and laboratories.
Capture Building or Room Pressure Profiles for Deeper Insight
The ACR Air™ Low Pressure Differential Logger records small changes in pressure across rooms, zones, or building envelopes, helping characterize how air moves within a space. By capturing pressure profiles over time, it supports meaningful analysis of airflow patterns and building pressurization performance.
This device is well suited to applications such as verifying directional airflow in isolation rooms, validating pressurization in cleanrooms or ERs, and assessing HVAC system effectiveness during commissioning or troubleshooting. With a ±125 Pascal range, wireless data retrieval, and rechargeable power, it supports efficient, unobtrusive deployment in both temporary studies and longer-term assessments.
Features
Placement is critical. The location of the pressure port or tubing directly affects what you're actually measuring. For example, in a large open warehouse, placing the tube at the front may show a significant pressure change when a door at the back is opened—because the space behaves as a single connected air volume. In contrast, in buildings with many partitions, hallways, or closed rooms, such an effect might be dampened or isolated.
To get meaningful results, place the tubing across the specific boundary you're trying to evaluate—such as between a corridor and a patient room, or between indoors and outdoors. Always document placement clearly and consider how air can move through the space when interpreting the data.
Balancing Comfort and Control: The Critical Role of Building Pressurization
Building pressurization plays a key role in comfort, energy use, and indoor air quality. Even slight negative pressure can cause drafts, moisture issues, and HVAC inefficiencies. This article highlights the value of monitoring pressure trends over time using tools like the ACR Air™ Low Pressure Differential Logger to identify imbalances and improve building performance.
