Airflow Instruments Micromanometers

Differential pressure is central to HVAC performance — too low and air delivery suffers; too high and energy costs rise. Airflow Instruments Micromanometers are designed to help you capture stable readings quickly, convert to velocity and flow as needed, and package results for reports.

What You Can Measure

• Static and Total Pressure: Validate fan curves, coil pressure drops, and filter loading trends.
• Pitot Velocity and Flow: Use pitot tubes to traverse ducts and calculate average velocity and volumetric flow.
• VAV and Control Diagnostics: Verify box operation, damper positions, and control setpoints during commissioning.
• Room Pressurization: Support directional airflow checks in healthcare and lab environments.

Key Features

• Fast Warm-Up and Auto-Zero: Helps maintain stable baselines between locations.
• Density Inputs: Temperature and barometric pressure entries support density-corrected calculations when required.
• Data Logging: Record time-stamped measurements, notes, and tags for clear traceability.
• Rugged Build: Field-tough construction supports daily use and transport.

Tips for Reliable Results

• Use Proper Ports: Confirm “static” versus “total” pressure connections to avoid measurement errors.
• Stabilize Readings: Allow stabilization, especially at low differential pressures.
• Traverse Method: Follow standard duct traverse techniques for representative velocity calculations.
• Calibration Discipline: Keep instruments within calibration and use field checks to spot drift.

Selection Guide

• Range/Resolution: Match expected pressures — especially critical for low-pressure healthcare or clean areas.
• Pitot Compatibility: Choose models and accessories that fit your pitot tube and duct sizes.
• Workflow: Consider models with Bluetooth and reporting apps if your team delivers detailed commissioning packages.

With repeatable pressure measurement and convenient data handling, these micromanometers help you diagnose issues faster and deliver clear, defensible results.
