Multi Function Ventilation Meters

Multi-function ventilation meters combine multiple sensors — velocity, temperature, humidity, and often CO2 or CO — into one instrument to help R&D teams capture a broader picture of indoor environmental performance. Swappable probes and data logging support flexible test plans, from ventilation effectiveness to comfort and energy studies. These meters streamline workflows by reducing equipment changes and centralizing data collection.

R&D programs often need to correlate airflow with thermal and moisture conditions, and in some cases gas concentrations. Multi-function ventilation meters bring these measurements together, helping teams build richer datasets with fewer device changes. By consolidating velocity, temperature, humidity, and optional gas sensors into a single platform, these instruments support efficient test planning and cohesive analysis.

Benefits for research workflows:

  • Multiple parameters in one device reduce setup time and complexity.
  • Swappable probes extend measurement range and applications without purchasing separate meters.
  • Data logging centralizes records, simplifying synchronization across parameters and test points.
  • Portable designs allow quick transitions between mockups, labs, and in situ studies.

Applications:

  • Ventilation effectiveness studies that link velocity fields with thermal comfort.
  • Moisture and condensation risk investigations supported by RH and temperature data.
  • Demand-control and IAQ research with CO2 or CO sensing (model dependent).
  • Education labs where students can see multi-parameter interactions in real time.

Integration tips:

  • Pair with capture hoods to verify volumetric delivery at terminals while logging environmental conditions.
  • Use micromanometers to add pressure diagnostics that align with airflow and comfort measurements.
  • Combine with thermal anemometers for detailed low-velocity mapping while tracking temperature and humidity.

TSI can help you select the right probe sets, ranges, and data interfaces for your research program. Calibration services support consistency across semesters, projects, and multi-site collaborations, helping teams build reliable, comparable datasets.
