Micromanometers

Micromanometers give response and facility teams the precision needed to verify low differential pressures that define HVAC performance. Whether confirming negative pressure in isolation areas or measuring filter pressure drop to plan maintenance, these meters deliver actionable data in minutes.

Core Uses

• Room Pressurization: Measure differential pressure between spaces to support directional airflow strategies for clinics, evidence areas, and containment zones.
• Filter Monitoring: Track pressure drop across filters to plan replacements and assess system impact.
• Duct Traverses: Pair with a pitot tube to calculate airflow in ducts during commissioning and troubleshooting.
• Building Envelope: Check pressure relationships across doors and vestibules during smoke purge testing and airflow diagnostics.

Key Features

• High Resolution and Stability: Capture low pressures typical of room-level control.
• Auto-Zero and Averaging: Reduce drift and smooth readings in variable conditions.
• Data Logging: Create a record for audits, incident reports, and work orders.
• Accessory Compatibility: Use pitot tubes and static pressure probes for a wide range of tasks.

Best Practices

• Tubing Management: Keep lines kink-free and equal in length for accurate differentials.
• Stabilize Readings: Allow time for readings to settle; use average functions when flow is variable.
• Reference Location: Place reference port in a stable zone to avoid noise and crossflows.
• Calibration: Maintain a regular, traceable schedule to support measurement confidence.

Selection Criteria

• Range and Resolution: Choose instruments that match expected pressures for your spaces.
• Environmental Suitability: Consider temperature and humidity conditions for field work.
• Interface and Export: Look for clear displays, units conversion, and easy data transfer.
• Durability: Protective housings and carry cases support frequent transport.

When micromanometers are part of standard operating procedures, agencies can validate conditions quickly, spot trends early, and document system performance across critical spaces.
