Handheld Anemometer for Wind Speed Temp Humidity, Digital Rechargeable Air Flow Gauge Meter

Before first use, open the battery cover, connect the battery (charge if needed). 3-in-1 Weather Meter: This upgraded wind speed meter allows you to quickly obtain critical environmental data including wind speed, wind temperature, humidity, and wind chill directly in the palm of your hand.

It's a must-have tool for any outdoor activity, such as shooting, sailing, kite flying, climbing, drone flying, and more; Rechargeable, Backlight and Flashlight Function:Our anemometer features an extra-large LCD backlit screen that allows you to measureHighly Accurate Wind Meter: This wind speed meter can measure wind speed ranging from 0.67 to 67.1 mph with an accuracy of +/- 2% of readings, while the wind temperature range is from 14 to 113 with a resolution of 0.1%.

It features 2 temp sensors and 8 vanes, making it sensitive to measure very low air flow in HVAC, duct vent, etc; data in the dark, a flashlight function to illuminate your path, and a type-c charging port to charge it with your charging device when needed.

It is for outdoor use; Rechargeable, Backlight and Flashlight Function:Our anemometer features an extra-large LCD backlit screen that allows you to measure data in the dark, a flashlight function to illuminate your path, and a type-c charging port to charge it with your charging device when needed.

It is for outdoor use; Tripod Hole for Mounting: The digital anemometer features a metal threaded hole on the bottom, allowing you to fix it onto a tripod for continuous wind measurement. This allows you to free your hands when flying drones, RC planes, wings, helicopters, and quads for long-distance shooting (Tripod not included); CFM Calculation Application: It can also assist in measuring cfm by using our precision anemometer to measure the wind speed and then multiplying it by the vent area to obtain the CFM (Air Flow in CFM = Wind speed x Duct Cross Sectional Area);
