Alnor Micromanometers

Differential pressure is foundational to ventilation research. Alnor micromanometers are designed to help labs measure small pressure changes with confidence and convert those readings into velocity when using pitot tubes or probes. Whether traversing ducts to validate models or diagnosing components for pressure drop, these instruments support a wide range of experimental needs.

Core capabilities:

• High-resolution pressure sensing for traverses, static pressure, and filter or coil pressure drop.
• Velocity calculation support with pitot tubes enables duct flow determination.
• Auto-zero features and temperature compensation (model dependent) help maintain stable baselines.
• Data logging and export options streamline analysis, reporting, and comparison across test runs.
• Rugged, portable enclosures withstand frequent setup changes in labs and field environments.

Use cases across R&D:

• Verifying computational fluid dynamics (CFD) predictions with measured pressure and velocity profiles.
• Measuring fan curves and system performance across operating points.
• Evaluating the impact of prototype components, louvers, or dampers on system resistance.
• Supporting teaching laboratories where students learn core principles of pressure and flow.

Integration in the R&D toolkit:

• Pair with capture hoods for cross-validation between volume-based and pressure-derived flow.
• Combine with thermal anemometers to map low-velocity regions not suitable for pitot techniques.
• Use alongside rotating vane anemometers for face velocity checks and volumetric estimates at grilles.
