Multi Function Ventilation Meters

Multi-function ventilation meters combine key HVAC measurements — air velocity, volumetric flow, temperature, and humidity — in one portable platform built for industrial environments. Interchangeable probes and smart sensing deliver flexibility across supply, exhaust, and process ventilation checks. Technicians can profile ducts, assess diffuser performance, and perform IAQ spot checks with a single instrument. Data logging and reporting capabilities support commissioning, troubleshooting, and ongoing optimization. Rugged construction, ergonomic design, and clear displays help reduce setup time and promote consistent results. With accessories for vane or hot-wire measurement, these meters adapt to varied airflow conditions found in manufacturing facilities.

Industrial HVAC teams need fast, reliable data across a range of tasks, from commissioning to routine checks and problem solving. TSI multi-function ventilation meters bring airflow, temperature, and humidity measurements together in a single, portable tool that adapts to changing test needs on the plant floor.

What You Can Measure

  • Air Velocity and Flow: Use hot-wire or vane probes to capture point velocities, traverse ducts, and calculate volumetric flow.
  • Temperature and Humidity: Verify thermal conditions and comfort indicators around production areas, AHU discharge, and makeup air.
  • Diffuser and Grille Performance: Profile supply outlets to assess throw, spread, and balance.
  • IAQ Spot Checks: Conduct quick surveys to complement building automation data and validate conditions in critical zones.

Designed for Industrial Use

  • Interchangeable Probes: Swap probe types to match duct sizes, velocities, and turbulence levels.
  • Rugged Portability: Durable enclosures and protective cases support frequent moves between equipment rooms and production spaces.
  • Clear, Backlit Displays: Read measurements at a glance, even in low-light mechanical areas.
  • Ergonomic Form Factor: Comfortable grip and intuitive controls support long shifts and repeated testing.

Data Handling That Drives Action

  • Onboard Logging: Capture time-stamped series during duct traverses and diffuser studies.
  • Guided Calculations: Convert point velocities into flow and summarize traverses with consistent methods.
  • Reporting Options: Export data to spreadsheets and templates to streamline commissioning and service documentation.

Operational Benefits

  • Faster Commissioning: Consolidate multiple tools into one meter to simplify site logistics and reduce setup time.
  • Better Troubleshooting: Cross-check airflow, temperature, and humidity data to narrow down causes of comfort or process issues.
  • Continuous Improvement: Use logged data to track changes after setpoint adjustments, filter changes, or equipment upgrades.

Use Cases

  • New System Startups: Validate airflow delivery against design values and create a baseline for facility teams.
  • Routine Verification: Spot-check key branches and outlets to confirm performance during seasonal transitions or production changes.
  • Energy Projects: Identify opportunities for fan speed optimization and improved control strategies by comparing measured flows to targets.
  • Process Ventilation: Assess capture velocities and local exhaust conditions to support operational goals.

Getting Started

  • Select probe types that match your common duct sizes and velocity ranges.
  • Request a demo to see logging and reporting workflows.
  • Ask a TSI specialist about accessories and kits tailored to your industrial applications.
