Airflow Instruments

Airflow instruments give teams the flexibility to measure velocity, volumetric flow, and pressure across ducts, hoods, clean benches, and open areas. In life sciences facilities, these measurements support cleanroom classification, fume hood assessments, and routine monitoring of critical spaces. Options include hot-wire probes for low-velocity laminar flow, vane anemometers for larger grilles, and pitot-based kits for duct traverses. With clear interfaces, data logging, and robust calibration programs, airflow instruments help standardize methods across sites and contractors — improving consistency, reducing investigation time, and supporting audit-ready documentation.

Comprehensive Measurement for Controlled Environments

Airflow defines cleanliness classes, containment performance, and user comfort. From low-speed laminar flow in biosafety cabinets to high-velocity exhaust risers, airflow instruments help quantify performance and support corrective actions. Choosing the right sensor and method for each location is essential to produce reliable, repeatable results.

Instrument Types

  • Hot-Wire Anemometers: High sensitivity at low velocities, ideal for laminar flow and clean benches.
  • Vane Anemometers: Rugged, fast averaging for diffusers and grilles.
  • Micromanometers with Pitot Tubes: Duct traverses for system-level balancing.
  • Multi-Function Meters: Combine velocity, temperature, humidity, and pressure for comprehensive surveys.

Use Cases

  • Cleanroom Classification Checks and Recertification
  • Fume Hood Face Velocity and Uniformity Tests
  • HEPA Filter and Terminal Diffuser Assessments
  • Duct Balancing and Energy Optimization
  • Root-Cause Investigations of Environmental Deviations

What to Look For

  • Accuracy and Resolution: Especially at low speeds below 50 fpm.
  • Probe Geometry and Reach: Access tight spaces and critical measurement planes.
  • Data Handling: Onboard logging, tags, and exports for traceable records.
  • Calibration Services: Documented calibration to support quality systems.
  • Durability: Field-ready instruments designed for repeated daily use.

Method Tips

  • Stabilize environmental conditions before measurement.
  • Use consistent traverse patterns and dwell times.
  • Calibrate on a defined schedule aligned with SOPs.
  • Capture enough points to represent airflow variability.
