Professional Digital Anemometer – HVAC Air Flow Meter with USB Data Logging & CFM Measurement

✅ FREE SHIPPING – Fast delivery within the U.S.

Product Overview

Designed for HVAC professionals, technicians, and ductwork specialists, this digital anemometer delivers accurate wind speed, air temperature, and air flow volume measurements essential for system balancing, ventilation testing, and duct performance analysis. Whether you're commissioning a new HVAC installation, troubleshooting airflow issues, or performing routine maintenance, this meter provides the precision data you need to get the job done right.

With the ability to input duct cross-sectional area and calculate CFM directly, this instrument eliminates manual calculations and speeds up your workflow. The extendable sensor handle reaches deep into ducts and vents, while the USB PC connectivity allows you to log and analyze data for professional reporting.

HVAC Applications

This anemometer is purpose-built for:

  • Duct Air Flow Measurement – Input duct dimensions and read CFM directly for supply, return, and exhaust registers

  • System Balancing – Verify design airflow at each diffuser, register, and grille

  • Ventilation Testing – Measure air velocity in ducts, plenums, and air handling units

  • Filter Pressure Drop Analysis – Monitor airflow changes before and after filter replacement

  • Exhaust Hood Testing – Verify capture velocity for kitchen, laboratory, and industrial exhaust systems

  • Commissioning & Retrofit Projects – Document airflow performance for new installations and system upgrades

  • Troubleshooting Airflow Issues – Identify blockages, leaks, or design deficiencies in ductwork

Advanced Functions for HVAC Testing

  • Average Flow Measurement – Take up to 12 readings across a duct face and calculate the average air flow value automatically – essential for accurate duct traverse measurements

  • 2/3 Max Flow Calculation – Specialized function for ductwork analysis and ventilation design verification

  • MAX/MIN Recording – Track peak and lowest readings to identify system fluctuations and instability

  • Data Hold – Freeze readings on screen for easy recording when working in awkward positions

  • Auto Power-Off – Preserves battery life after 5 minutes of inactivity

  • Low Battery Indicator – Clear warning when power is running low

PC Data Logging for Professional Reports

Transform this handheld meter into a complete documentation tool:

  • Connect via USB to any Windows PC

  • Monitor real-time wind speed and temperature readings on screen

  • View dynamic trend graphs for system performance analysis

  • Save and export data for client reports, commissioning documents, and service records

  • Compatible with Windows 98/ME/2000/XP (32-bit)
