From airflow mapping in a prototype enclosure to verifying setpoints in a cleanroom, reliable air velocity data underpins many R&D activities. TSI air velocity meters are designed to help researchers get the right measurements with minimal friction. Sensitive sensing elements support low-flow detection, while robust construction holds up under frequent use across buildings and test sites.

These meters emphasize usability: clear displays, straightforward menus, and ergonomic form factors that make extended sessions more comfortable. Built-in logging supports continuous and spot measurements, with time stamps and annotations that simplify collaboration and reporting. Export options help you pull data into spreadsheets, scripts, and analysis tools to compare runs, calculate uncertainty, and summarize findings.

Common R&D applications:

  • Velocity profiling in ducts and environmental chambers.
  • Fume hood face velocity checks and enclosure performance studies.
  • Lab ventilation surveys to assess distribution and balance.
  • Model validation by comparing measured and predicted airspeed.

Why research teams choose TSI velocity meters:

  • Measurement sensitivity for low-flow regimes common in lab environments.
  • Repeatable readings that support detailed comparisons and trend analysis.
  • Streamlined operation for rotating staff and cross-functional teams.
  • Portable durability for daily use in labs and field settings.

Air velocity meters are a foundation of ventilation measurement. With TSI, you gain instruments that help convert complex airflow behavior into clear, defensible data — supporting faster iteration cycles and stronger evidence for design and process decisions.
