Airflow Instruments Micromanometers

Low differential pressure drives many critical decisions in industrial facilities. Whether you are confirming positive pressure in production areas, negative pressure in containment zones, or duct velocities during traverses, micromanometers provide the sensitivity and stability needed for trustworthy results.

These handheld instruments measure very small pressure differences and, when paired with pitot tubes or flow grids, calculate velocity and volumetric flow. Many units also capture temperature and barometric inputs, improving the quality of derived measurements. A wide, backlit display and straightforward menus keep the focus on the measurement, not the interface. Field-ready features like magnetic hanging straps and protective boots support hands-free reading and durability in mechanical rooms or on lifts.

Typical use cases:

• Verifying room pressurization between clean areas and corridors
• Tracking filter loading to plan changeouts and reduce unplanned downtime
• Performing duct traverses for commissioning and rebalancing
• Measuring stack or process exhaust performance
• Diagnosing system issues such as blocked coils or dampers

Selection guidance:

• Pressure range and resolution aligned to cleanroom or general HVAC tasks
• Compatibility with pitot tubes, static pressure tips, and flow grids
• Built-in calculations for velocity, flow, and density correction
• Data logging capacity, tagging, and export formats
• Ruggedness for jobsite use and regular calibration workflows

When micromanometers are part of a larger toolkit — including capture hoods, anemometers, and rotating vanes — teams gain complete visibility into airflow delivery from source to space. This helps maintenance and engineering prioritize the right fixes and document outcomes clearly for audits and internal reviews.
