Specifications:

• Multifunction Pro Anemometer:Wind Speed, Wind Temperature, Wind Chill, Low battery indicator on bright backlit LCD screen. BT-100 is a portable wind speed guages can accurately measure air speed in 5 units: m/s, km/h, ft/min, knots, mph. Wind Temp in C/F(Degree Celsius/Fahrenheit)
• Accurate Wind Meter:Wind Speed Meter for measuring wind speed range 0.67 to 67.1 mph(+/- 2% of readings), Wind temperature -10 to 60C,14F-113沈(+/-2C,35.6F); Resolution 0.1m/s; 0.2C. 2 temp sensors and 8 vanes makes this air velocity meter is sensitive to measure very low air flow in HVAC installation, duct vent. A good helper in CFM calculation. Air Flow in CFM (Q)=Wind speed(V) x Duct Cross Sectional Area(A)
• Tripod Hole for Mounting:There＊s a metal threaded hole on the bottom of the digital anemometer, so you can fix it on a tripod for continuous wind guages. To set your hands free when you fly drones, rc planes, wings, helicopters and quads, long distance shooting.
• Anemometer Case Included:It's a light weight, pocket size airspeed Meter, portable for you and your family to measure outside for outdoor activities, such as: shooting,Boat Sailing, Kite flying, Climbing, Drone driving etc.
