require longer periods particularly after prolonged exposure to very high or very low humidity. WBGT requires about 8 minutes to reach 95% accuracy and about 15 minutes to reach 99% accuracy after exposure to large environmental changes. Every Kestrel Meter features a large, 1” impeller mounted on a sapphire jewel bearing, which means it starts rotating with the slightest puff of air. For superior accuracy, the impeller housing can rotate in the unit. The patented impeller is user-replaceable by simply pushing it out with your thumbs, which means it can easily be replaced if it is damaged or worn. The measurements from the wind impeller are taken magnetically. The impeller is not glued or attached to the unit. Because every new impeller is calibrated in the wind tunnel at the USA factory, if your application demands regular calibration, simply pop in a new impeller and the Kestrel Wind Meter is restored to like-new factory calibration standards. Wireless range up to 100ft. Connection requires optional USB data transfer cable or Kestrel Link Dongle or Kestrel LiNK app. Employs Kestrel Link protocol for data transmission with Link supported devices. (Kestrel LiNK for iOS/Android, Kestrel Link for PC/MAC). View your live & historical data on your mobile device - up to 100ft away from the Kestrel (requires the LiNK wireless communication option). Now we need to select our rifle or ammunition combination from the menu. Scrolling down from Wind will highlight Gun, and scrolling right and left will allow you to select the one you are going to use. You do not need to do anything to select the correct one, as once it is on the screen it will change the solution to suit the one displayed.

Kestrels have been put to the test in some of the harshest conditions on the planet. U.S. Special Forces, combat weather teams, HazMat crews, wildland firefighters, smoke jumpers, Mt. Everest expeditions and auto pit crews are just a few who rely on a Kestrel to provide them with the crucial environmental data they need. Watch any on-screen meteorologist during a hurricane, and you’re sure to spot a Kestrel in action. Be your own meteorologist, anywhere in the world, with a Kestrel 5500.

It’s as easy as that really. Since the word anemometer isn’t the easiest to say or spell, wind speed measuring devices are often referred to as a wind gauge or wind speed meter.

Of course, now that you have more than one target selected you are not able to adjust the range to the target as you did earlier, as scrolling left and right now changes the selected target, not the range. Most wind meters nowadays are digital wind meters. This means that the data from the anemometer is displayed on a screen. In the early days, people had to count the number of rotations of the anemometer to determine wind speed. Anemometers Integrated into Weather Stations

All measurements except those based on relative humidity respond accurately within 1 second. Relative humidity and all measurements which include RH in their calculation may require as long as 1 minute to fully equilibrate to a large change in the measurement environment. Display updates every 1 second. The word anemometer actually originated from the Greek word “anemos”, which translates to “wind”. Nowadays anemometer is still the most commonly used term for referring to a wind speed measuring tool, especially in the scientific field. The second type: the vane anemometer is the most used one in handheld anemometers. This wind meter consists of blades, almost like a propellor. The blades face the wind directly, like a windmill.
