ALLmeter Handheld Digital Anemometer Wind Speed Meter with Temperature | Accurate Airflow Measurement for HVAC, Outdoor, Sailing & Field Use | Backlit LCD

["【HVAC AIRFLOW TESTING MADE SIMPLE】 Weak vents? Uneven room temperatures? Measure airflow instantly and identify underperforming ducts, registers, diffusers, and exhaust vents before they become costly HVAC problems. Displays airflow in ft/min and m/s—the units HVAC professionals use every day. Ideal for homeowners, maintenance teams, and HVAC technicians.","【DETECT LOW AIRFLOW WITH PROFESSIONAL ACCURACY】 A sensitive 6-blade impeller starts measuring airflow as low as 0.3 m/s, making it ideal for weak vent diagnostics and low-speed air circulation checks. Measures wind speed from 0.3–30 m/s (0–5860 ft/min) with ±5% accuracy and temperature from 14°F to 113°F. Monitor airflow and temperature simultaneously for faster troubleshooting.","【MAX, AVG & REAL-TIME MODES FOR BETTER DECISIONS】 Switch instantly between live readings, maximum wind speed, and a 4-second rolling average. Use MAX mode to capture peak airflow, AVG mode for stable system evaluation, and real-time mode for changing conditions. A practical tool for HVAC inspections, ventilation testing, fieldwork, and outdoor measurements.","【BEAUFORT SCALE, WIND CHILL ALERT & 5 WIND SPEED UNITS】 More than just a wind speed number. The built-in Beaufort Scale helps quickly understand wind conditions for drone flying, hiking, camping, sailing, and shooting activities. Automatically displays a Wind Chill alert when temperatures fall below freezing. Supports m/s, km/h, ft/min, knots, mph, plus °C and °F temperature units.","【READY TO USE RIGHT OUT OF THE BOX】 Includes 3 AAA batteries so you can start measuring immediately. Features a backlit LCD display, low battery indicator, automatic or manual power-off options, and lightweight ABS construction. Compact enough for your pocket yet reliable enough for daily HVAC service calls, outdoor activities, and professional field use."]
