12 best anemometers

Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

Anemometers are used to determine the air flow rate. It is important to calculate the heating draft, the performance of the ventilation or air conditioning system, and the efficiency of exhausting harmful gases. They are also used on sailing yachts or when riding on a surfboard to determine the strength and direction of the wind. We figured out the features of this equipment and studied customer reviews, so we are ready to offer you the TOP-12 best anemometers, which you should pay attention to if you need such an apparatus.

How to choose an anemometer

Before studying the TOP-12, we note the main criteria for choosing an anemometer:

1. Device configuration. There are devices in a single case, and there are devices with a separate execution of the computing and reading devices. The first option is useful if there is easy access to the sampling sites at the operator's outstretched arm. When the ventilation or exhaust grille is high, it is practical to use a wire-mounted sensor (attached to a telescopic rod) to feed it to the reading point and observe the result below.
2. Measurement range. Some models are capable of measuring wind speed in the range of 0-10 m / s. This is enough to check the air conditioning system. When you have to test the operation of ventilation or hoods, then choose anemometers designed for 0-30 or 0-50 m / s.
3. Sensitivity. This is the minimum threshold for air movement that the device can detect. The indicator ranges from 0.1 to 0.9 m / s. Sensitivity is important where it is required to determine the presence of even the smallest blowout.
4. Possibility of measuring temperature. Most devices are capable of recording the temperature of the passing stream. Only some can measure only positive temperatures, while others have sensitivity to negative temperatures within -10 … -20 degrees.
5. Error. Anemometers are able to measure the speed of air flow with an inaccuracy of 0.1-0.5 m / s, which is an error of 1-5%. If deviations from the true values ​​are not so important (draft of the fireplace, ventilation of corridors), then a device with an error of 5% is sufficient. When it comes to measuring the air flow in living quarters or places of livestock breeding, devices with a minimum error are needed.
6. Autonomy time. All anemometers are battery or rechargeable. The autonomy period varies from 8 to 60 hours. Consider this if there are large volumes of measurements ahead with daily checks.

Anemometers are also divided according to the way they read the gas flow, where there are three most common categories, into which our review is divided.
