Anemometer is a speed measurement tool. It’s designed specifically to measure wind speed and air flow rate. However, it’s not weird that a single anemometer comes with other measurements. It benefits you to cover as many measurements as possible.
There is a broad application of this instrument including for home use, HVAC, sailing, paragliding, drone flying, kite surfing, kite flying, ballooning, storm chasing, golf, athletics, etc.
For home use, you could use it as an independent weather station. This requires you to install other weather sensors as well. In agriculture, it checks the wind speed before the spraying. While in construction, it’s important to access the wind before working with cranes.
There are a large number of anemometers on the market which may lead you to be frustrated to choose from. It can be the cup model or the wire hot type or the handheld/impeller type. Each model is great to use for a specific purpose. Therefore, you have to pick the right model for your needs.
In this article, we are going to break them down as completely as possible. The following is the review section of the top 10 anemometers that we gather from the market. Scroll further to read the buying guide and some important information about anemometers.

What to Consider When Buying An Anemometer
1. Select the Right Type
When buying an anemometer, it’s always important to select the right type.
There are several types of anemometer, however, we find 3 of them are the popular ones in today’s market: cup anemometer, propeller/impeller anemometer, and hot wire anemometer.
– Cup Anemometer
As the name suggests, it employs several cups that are mounted on the arms (each cup is mounted on one arm); at the same time, the arms are mounted on a single rotating shaft. The cups are separated in an equal distance vertically. When the wind passes the cups, the cups will rotate.
Since it’s not portable, this model is right to use for home use. You could use this also for storm chasing, sailing, and firefighting but it must be able to be mounted on the top of the vehicle.
– Propeller/Impeller Anemometer
The most used propeller anemometer is the handheld model that we can easily find on the market. This handheld is portable and easy to carry.
There are two models of the handheld anemometer: built-in propeller (the propeller is integrated into the body of the anemometer) and separated propeller (with probe). The model with the probe can be seen on the image beside.
Due to great mobility, this built-in impeller model can be used for almost all applications. Simply, it fits in the pocket. However, it would not be a great idea to use this model for in-duct airflow measurement in HVAC.
– Hot Wire Anemometer
Hot wire anemometer (HWA) looks simpler but the way it works is more complex than the cup and vane anemometer. The idea of this anemometer is based on the correlation between heat transfer and fluid velocity.
This type of anemometer is ideal for HVAC especially if it doesn’t matter about the airflow direction such as the wind that passes through the ventilation; the airflow direction is monotonous. It’s commonly used for in-duct airflow measurement.
Accuracy is critical, especially for a serious application. However, in some cases, you could rely on the anemometer that provides some degree of accuracy. It may not precisely accurately measure, but works well. If you pursue the accurate one, you have to rely on the certificate from a trusted authority.
3. It Covers Other Measurements
It’s always a good idea to pick the anemometer that comes with other sensors such as a thermometer, barometer, etc. This is important to suit your need. For example, the anemometer should be built-in with an altimeter, compass, barometer, and thermometer for hiking. Moreover, the screen should display the windchill temperature as well. In order to be suitable for sailing, the screen should display the Beaufort scale.
Despite cup anemometer, it would be great if portable. If it’s possible to be mounted on the vehicle, then it’s good. A handheld anemometer is the best overall of this thing. It’s possible to fit in the pocket. A small bag would be suitable to store it. In the case of a stationary anemometer, you could mount it on the tripod.
5. Water and Dust Resistant
Carrying an anemometer during outdoor activity requires extra attention to the durability of the product. Snow, rain, and mud can damage the instrument. A tested anemometer should exceed this requirement. In this case, an IP-rated anemometer can be relied on to carry.
