An Anemometer is used to measure air speed with some versions also measuring air flow. There are different types of anemometers depending on how you are planning to use them and your application. If you want to measure wind speed outside and you are not concerned about wind direction then a Cup anemometer would be the meter you are looking for. Vane and mini vane anemometers must be held in the direction the wind is coming from to get the most accurate reading possible, these units are used both inside and outside and can measure a wide variety of air speeds. To measure very low airspeeds a hot wire anemometer is best suited to your application, these units are extremely precise and work wonderfully at low air speeds, they are quite delicate however so care must be taken not to damage the sensor when using them.
Air flow meters can determine the air flow, which is the volume of air not just the speed of the air; these are extremely useful in HVACR applications. When taking air flow measurements the accuracy of your results will be greatly increased when using an Air Flow Hood which is used to capture all the air flowing from an outlet.
We also have available wind data loggers for recording the air speed over time; this can be used to assess the amount of wind an outside site is exposed to over a long term basis. This data is saved and then graphed to your computer for further analysis. Another way of measuring outside air speed and direction is by using one of our weather stations, these can also be used to record a number of different weather parameters giving you a versatile weather recording option.
