Digital Wireless Anemometer with APP via Bluetooth, Handheld Wind Speed Meter Wind Gauge for Measuring Wind Velocity/Temperature with Backlit, Max/Min/Avg(INFURIDER YF-866APP)

Basic anemometer seems to work as intended. When it arrived, the blade disk was very slightly but clearly out of balance. A small dab of Elmers glue on the "high" side when the disk came to rest appears to have fixed the problem. I assume this would have only been a problem in very light winds.

Dang this kept me from needing to hire some HVAC company to come out and help troubleshoot poor AC duct performance.Was able to use this to figure out how to get as much cold AC air upstairs as possible. I don't use if for extremely precise scientific variation calculations...LoL (tried to use a bunch of big words) so cannot say for 100% that it is like scientifically precise...but it measured air flows from my ducts and at the cold air intakes in a consistent manner...which was exactly what I needed.It also has a digital thermometer on it, that seemed pretty accurate too...so kind of a nice additional option.

Battery life is good. Tripod is flimsy but works. I add some weight to it to keep from blowing over.When long distance shooting, it's just as accurate as a few competitors $300 units.I also use it to monitor wind speed when running SAR operations with my drone. No complaints. The back-lit LCD is a bonus.

The app doesn't always work.

Great device. Glad I bought this. 1/4 x 20 female on bottom allows mounting outside so I can monitor wind speed on my android devices. Light weight and great as a hand held device also. Definitely a good buy.

Also I'm not sure wind chill really worked either. Temperature stayed the same regardless of wind speed.

What a fun device. And... it is very informative/educational. Not information that is life shattering but knowing how strong the wind is blowing is just plain fun to play with. This tool does a very good job of supplying that information for you. There are a lot of reasons for wanting or needing to know the wind velocity and this will do that for you at a very affordable price.The blades are very well balanced and are safely placed in a cage. The cage does not impede any of the air flow so readings will be very close to accurate. There is an LCD screen that will provide wind speed as well as temperature. You can choose between "F" or "C" for temp and the wind speed readout is also selective. It can determine "AVG" speed if you want to select it. It will also give you minimum and maximum speeds. The screen can be backlit if needed. There is a camera mount socket under the handle to mount on a tripod.Assembly is well done, and it feels like a quality device. It feels good in hand and is easy to use. Reading the screen is very easy as it is not cluttered with unwanted or unneeded information.Comes in a brown box with the device, a short tripod, charge cable, screwdriver to remove the door to install the included AAA batteries (2) and a case to store it all in as well as an instruction manual.We are enjoying this and will be using it on our various camping trips.

The INFURIDER anemometer, besides measuring wind speeds, can also capture the air temperature.The device provided accurate and reliable readings shown on its backlit LCD screen.The INFURIDER anemometer is lightweight and small in size so it can be easily transported wherever you go. It comes with a carrying case, a small screwdriver for changing batteries and even a small tripod.I mainly use it to test computer fans airflow, but it has many applications, such as checking outside conditions, AC unit, HVAC, drone piloting, climbing, shooting, boat sailing and even flying a kite.The INFURIDER anemometer can display wind speeds for any of these activities in 5 different units of measure and the temperature in degrees Celsius and Fahrenheit.This anemometer works on 2 AAA batteries, which are included with the unit. It has an auto power-off functionality and also the LCD backlight automatically goes off to help save battery when not in used.The INFURIDER is fairly priced, lightweight and accurate anemometer, that works very well for different applications.It has a clear display that provides various readings, helping users to make appropriate decisions.
