Thanks to Kestrel's sensitive impeller technology, you get accurate wind speed info. The Kestrel user replaceable impeller makes it easy to replace in seconds if damaged. Like all Kestrel meters, the waterproof casing allows you to gauge the temperature of water and snow, as well as open air. The Kestrel 3500NV portable weather station with Altitude and Barometric Pressure combines a full color display with the power of a complete weather lab in a single instrument. This portable weather meter offers a very bright display for easy viewing, is compatible with Kestrel's optional weather sensor kits, and includes alkaline batteries.

Accuracy also depends on where you plan to use the device. For example, if you are measuring airflow in a laboratory then accuracy is extremely important as any discrepancies can have significant effects on experiments. However, for personal use or general home purposes then it doesn’t need to be that accurate and so analog anemometers would suffice just fine.The Kestrel 2000 meter takes the minimum amount of data for farmers using Xtendimax and while it's not the best option before you spray, it is the least expensive and does cover the bare minimum requirements without the access to standard anemometer towers! Uses Portability: Handheld anemometers are small and lightweight, making them easy to carry around. This makes them perfect for use in fieldwork or other on-the-go applications.

Anemometers are typically accurate to 0.05 meters per second (m/s). How to calibrate an anemometer?

Make IIs

Anemometers can be stand-alone devices, or built into weather stations. Although both are considered accurate, the accuracy of the anemometer is dependent on how you use it.

Handheld wind speed weather station meters and handheld weather stations measure the velocity, force, or speed of wind. Different handheld wind meters use different methods to calculate the measured values. The Kestrel 3550FW digital unit paired with the free Kestrel app puts powerful tools for monitoring, logging, and sending important weather information, like measures wind speed, temperature for making the most informed decisions for fire management strategy. CE certified, RoHS and WEEE compliant. Individually tested to NIST-traceable standards (written certificate of tests available at additional charge). This sleek beast is waiting for you to claim it. Take the helm with confidence knowing its two smooth SA-3110 computer-controlled turbines are there with you every step of the way, completely silent even at low speeds, so you can keep your focus on the wind. Air pressure that would be present in identical conditions at MSL. Station pressure compensated for local elevation provided by reference altitude. Requires accurate reference altitude to produce maximum absolute accuracyConvenient and reliable, the Kestrel 2000 is the perfect tool for kite surfers, sailors and other outdoor enthusiasts. It is also ideal for farming & agriculture. Kestrel 2000 Anemometer and Temperature Meter Key Features In addition to the factors mentioned above, it’s also important to consider how well a handheld anemometer can handle wind speeds. Some devices will measure high wind gusts while others only cover low-speed measurements with accuracy levels in between these two options. Depending on your job requirements and preferences for certain conditions, you might want something that has more adjustable settings than simply 0-30 mph. Digital or Analogue Communicate the pressure or load in the sail. If the pressure or load is decreasing then inform the skipper and change your angle (sail higher) for more load. If the pressure or load is increasing, then inform the skipper and sail lower.
