Why This Anemometer Stands Out
This is a practical, no‑frills tool built for real‑world use. It gives you:
Wide wind speed range (0.3–30 m/s) with ±5% accuracy – reliable enough for professional checks, yet simple enough for DIY enthusiasts.
Temperature accuracy within ±2°C – perfectly adequate for ambient air monitoring in HVAC, greenhouses, or workshop environments.
Lightweight design at just 153g (including batteries) – easy to hold, carry, and use with one hand.
Low power draw (~3mA) – your AAA batteries last longer, saving you money over time.

| ✔ 5-in-1 Wind Speed Measurement – Instantly switch between m/s, km/h, ft/min, knots, and mph to match your project needs. Whether you're tuning HVAC systems, checking ventilation, or setting up outdoor gear, you get the right unit at the press of a button. | ✔ Built-in Temperature + Wind Chill Indicator – The integrated NTC thermometer reads from -10°C to 45°C (14°F to 113°F). When the temperature drops below 0°C, the display automatically shows a wind chill icon – a critical alert for anyone working in cold environments. | ✔ Data Memory That Works for You – Capture maximum (MAX) and minimum (MIN) readings with one tap, plus a 15‑second rolling average (AVG) to smooth out gusty fluctuations. No more guessing – you get reliable numbers for troubleshooting or reporting. | ✔ Backlit Display with Auto-Off – Press the backlight key for a bright, clear readout in dark ducts or dim job sites. The light shuts off automatically after 15 seconds to save battery. And with both manual and auto power-off, you stay in control of power usage. |
Who Will Love This Tool
HVAC Technicians – Verify airflow in ducts, vents, and diffusers quickly.
Facility Maintenance Staff – Spot check exhaust fans, air handlers, and drying systems.
Outdoor Enthusiasts – Measure wind speed for sailing, kite flying, or camping site selection.
Grow Room & Greenhouse Operators – Monitor circulation fans and temperature for plant health.
Weather Hobbyists – Log local wind conditions with consistent, repeatable readings.
