[Precise Wind Meter] Anemometers measure wind speed in 5 units: m/s, km/h, ft/min, knots, mph, with 12 Beaufort scales, and detect air temperature (14°F to 113°F). [Multi-Function] High precision pressure sensor; measures air speed, wind speed, and temperature; temperature unit selection in °C or °F; equipped with 6 sensitive vanes for HVAC installation, CFM calculation, and duct vent measurements. [Backlight Function] Allows operation in dark environments; manual or auto power-off option; automatically powers off after 5 minutes of inactivity. [Mini Size and Portable Design] Compact and lightweight for easy portability; fits in a pocket; includes an orange protective case for added protection and a wrist strap for secure handling in strong winds. [Various Applications] Provides quick measurement for analyzing environmental conditions; ideal for industrial and home use, such as measuring wind speed, fan airflow, computer CPU fan temperature, as well as for windsurfing, sailing, fishing, drone flights, and mountaineering. Digital Anemometer Functions: 1. Airflow velocity and temperature measurement 2. Max/Average/Current airspeed measurement 3. Temperature unit selection (°C/°F) 4. Five airspeed units: m/s, km/h, ft/min, knots, mph 5. Wind chill indication (when temperature is below 0°C) 6. Manual or automatic shutdown (device powers off after 14 minutes of inactivity) 7. Low battery indicator Specifications: Air Velocity: Range: 0–30 m/s, 0–5860 ft/min, 0–55 knots, 0–90 km/h, 0–65 mph Resolution: 0.1 m/s, 19 ft/min, 0.2 knots, 0.3 km/h, 0.2 mph Threshold: 0.1 m/s, 39 ft/min, 0.1 knots, 0.3 km/h, 0.2 mph Accuracy: ±5% Air Temperature: Sensor: NTC thermometer Range: -10°C to 45°C (14°F to 113°F) Resolution: 0.2°C, 0.36°F Accuracy: ±2°C, ±3.6°F Applications: Suitable for home, weather enthusiasts, or professionals to accurately measure air velocity and air temperature.
