Alnor Micromanometers

Differential pressure is a foundational measurement in HVAC and process ventilation. Alnor micromanometers give TAB contractors and facility teams the tools to turn small pressure readings into meaningful airflow data that drives system performance.

Measurement capabilities:

• Differential pressure: High-resolution sensing for static, velocity, and total pressure at taps, across filters, and along fans and coils.
• Airflow calculation: On-screen functions for pitot traverses convert pressure to velocity and volume flow, with user inputs for duct dimensions, air density, and k-factors.
• Trend and verify: Logging and time-stamped data enable trending across maintenance cycles and after system adjustments.

Field-ready design:

• Clear interface: Guided prompts and logical workflows help technicians move through setup, traverse sequences, and calculations efficiently.
• Rugged and portable: Durable housings and protective cases support daily field use across large facilities.
• Connectivity options: Export measurements to support commissioning reports, SOP documentation, and audit packages.

Industrial applications:

• Duct traverses: Validate airflow in main trunks and branches to support balancing and fan speed optimization.
• Filter and coil diagnostics: Measure pressure drop to assess condition and support maintenance planning.
• Fan performance checks: Compare measured vs. expected values to identify issues like belt slip, damper position errors, or fouling.
• Room pressurization: Verify differential pressure between spaces such as gowning, production, and support areas.
• Exhaust and hood assessments: Combine pressure with velocity measurements to evaluate capture effectiveness and airflow delivery.

Best-practice guidance:

• Use appropriate pitot tubes for duct size and velocity range; follow established traverse patterns.
• Apply temperature and density corrections to reflect actual site conditions.
• Stabilize readings and average as needed, especially in ducts with turbulence or complex geometry.
• Calibrate regularly to maintain measurement confidence and align with internal quality protocols.

Results that matter:

• More precise balancing and control tuning that can help reduce energy consumption while meeting environmental targets.
• Better visibility into system performance for faster troubleshooting and resolution.
• Documentation that supports quality systems and external audits when ventilation characterization is required.
