  • HVAC Airflow Testing Tool Measure air velocity at vents, registers and ducts to check airflow performance, detect weak airflow and support HVAC inspection. Designed for technicians, contractors, installers and building maintenance professionals.
  • Accurate Air Velocity Measurement Equipped with a sensitive 6-blade impeller, this digital anemometer measures airflow from 0.3-30m/s with temperature monitoring, helping diagnose ventilation issues and HVAC system performance.
  • Real-Time, MAX & Average Modes Monitor current airflow, maximum airflow and average airflow readings. These measurement modes help technicians analyse airflow changes during duct testing, system balancing and maintenance service.
  • Professional HVAC Measurement Functions Supports five wind speed units including m/s, km/h, ft/min, knots and mph with F/C temperature switching. Suitable for HVAC inspection, ventilation testing and air conditioning maintenance.

Description

Measure airflow instantly at vents, registers, ducts, and exhaust systems to detect underperforming areas. Avoid uneven temperatures and inefficient HVAC operation. Suitable for homeowners, maintenance teams, and HVAC technicians. Detect airflow as low as 0.3 m/s with ±5% accuracy. Measures wind speed 0.3–30 m/s (0–5860 ft/min) and temperature 14–113°F (±2°C / ±3.6°F). Simultaneously monitor airflow and temperature for reliable diagnostics. Choose the mode that fits the task: MAX captures peak airflow, AVG calculates a 4-second rolling average for stability, and Real-Time tracks live changes. Ideal for vent registers, ducts, and HVAC inspections. Use this anemometer for drone flights, sailing, hiking, kite flying, and other outdoor activities. The Beaufort Scale and Wind Chill alert provide intuitive, actionable wind information for safe outdoor decisions. Will this anemometer work for HVAC systems? Yes! This anemometer is perfect for checking airflow in HVAC systems, ensuring accurate readings for both residential and commercial settings. Can I use this device outdoors for hiking and boating? Absolutely! This handheld anemometer is compact and portable, designed for use in outdoor activities like hiking, boating, and sailing. How accurate is this wind meter? This anemometer provides highly accurate wind speed measurements with an accuracy of ±5%, ideal for both professional and personal use. Does it measure temperature as well? Yes! It measures both wind speed and temperature, providing a comprehensive reading for a wide range of outdoor and indoor applications. Who is this anemometer designed for? HVAC technicians, homeowners, maintenance professionals, drone pilots, sailors, hikers, archers, and anyone needing accurate, portable wind and temperature measurements.

Compact and Useful Wind Meter for Airflow Checks
This digital anemometer is a handy little tool for checking wind speed, airflow from vents, fans, ducts, or outdoor conditions. It is compact, lightweight, and easy to use, with a backlit display that is simple to read in different lighting. I like that it can show different wind speed units, temperature, wind chill, max readings, and average readings, which makes it useful for both practical testing and general outdoor use. The readings seem accurate and consistent, and it is nice that the batteries are included so it can be used right away. The plastic body is lightweight and fine for normal use, though I would be careful carrying it loose in a bag since the small fan/propeller does not appear to have a protective cover. Overall, it is a good value and a useful tool for HVAC checks, drone flying, boating, hiking, or just testing airflow around the house. ... show more

Works great so far
This little Anemometer is pretty nice! The screen is backlit for use at anytime and lighting conditions. You can turn off the light to conserve batteries. You can change the windchill temperature between imperial and metric. You can measure windspeed in 5 different units of measurement. You can set it up to get an average windspeed measurement over 10 minutes before it auto shuts off. You can also set it to measure the max windspeed. It's useful for HVAC techs to measure air flow from vents. Environmentalists can use it gather data in whatever area they are in. Hikers, kayakers, boaters, etc can use it for fun. I'm using it to help air flow of fans. It comes with batteries. Just double check them because one of mine came with a dent. Construction is okay. It's a plastic body, so it doesn't feel the greatest, but it would probably survive a few drops. It doesn't give a waterproof rating, so I wouldn't suggest getting it wet. It seems pretty accurate. It will save your settings when you turn it off, but it will not save your data, so it's definitely not something you can leave for extended periods of time. For $19, I think it's a good value for the money. ... show more
