BTMETER Digital Wind Speed Anemometer Handheld, Wireless Bluetooth Vane Meter for Chill, Speed, Temperature Monitor BT 100APP

【Bluetooth Anemometer】BT-100APP is an upgraded version of BT-100, equipped with a new Bluetooth module and a customized APP. It supports wireless pairing with iPhone/Android phone. You can remotely control and monitor wind speed data in real time via your phone, and easily export data as Excel or TXT files for convenient recording and analysis. 【High Accuracy】Wind meter measures air velocity range: 0.3 to 30 m/s, accuracy: ±5%, wind temp: -10°C - 45°C (℃/℉ switchable), accuracy: ±2°C. Equipped with 8 sensitive wind blades and 2 temperature sensors, it quickly captures even the slightest airflow changes for precise data. When the temperature drops below 0°C, the screen automatically displays a wind chill indicator icon. 【3 Modes & 5 Units】 Wind speed anemometer offers 3 measurement modes: AVG, MAX, and MIN, along with 5 wind speed units (m/s, Km/hr, Ft/min, Knots, Mph) that can be switched freely to meet diverse measurement needs across different scenarios. 【User-Friendly Design】 Weighing only 135 g, digital anemometer comes with a lanyard and a storage bag for lightweight portability. The 1/4-inch standard screw hole at the bottom is compatible with most tripods, freeing your hands for long-term continuous testing. Backlight for clear readings in dim environments. Auto power-off time can be adjusted via the APP to effectively extend battery life. 【Wide Applications】 Air flow meter is ideal for various outdoor activities such as long-range shooting, hunting, sailing, kite flying, and drone piloting. It is also commonly used to measure low airflow in HVAC installations and duct vents. Simply multiply wind speed by the duct cross-sectional area (CFM = wind speed נarea) to easily calculate airflow volume.
