Kestrel 3550AG Spraying Weather Meter
Avoid spray drift and maximise application results with this portable and connected handheld weather meter. Off-target pesticide drift can not only cause damage to nearby vulnerable crops but also pose a serious threat to people, livestock, wildlife, and the surrounding community.
Farmers put themselves and their operations at risk every time they spray a field without documenting the wind speed and environmental conditions. The 3550AG with Bluetooth Connectivity makes it easy to instantly capture and log accurate, field-level weather data with just one-click.
No matter the size of your operation – effective herbicide and pesticide application is critical to your success. Prevent drift, eliminate waste, ensure safety and effectiveness – it all starts with monitoring your conditions.
Impeller:
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 – 0.48 km/h to be exact! This 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. The Kestrel 3550AG can easily be switched between °F, °C, mph, km/h, ft/min, m/s, knots, Beaufort, and Delta T.

Field-Level Environmental Monitoring for Reliable Decision-Making
It is critical to measure relative humidity, wind speed and wind direction at field-level to minimize waste and maximize safety when spraying. The on-site weather at time of application has a significant impact on the risk of drift. Best management practices include checking weather at the site of application to ensure safe and effective spraying. With a built-in digital compass, the 3550AG measures all relevant environmental conditions for spraying including wind direction.
Experts urge applicators to take measurements at the field location and make decisions from accurate, onsite information. It’s important to measure wind speed at the height of sprayer booms and not rely on readings from the local airport which could be dozens of miles away. The data from remote weather stations do not accurately reflect the conditions at your specific site.
"If you face any litigation, they will go to nearest airport and get wind speed there," [if no other record exists] "Airfields are typically flat, so the wind speeds are higher there and taken at heights much greater than the boom height of your sprayer. It’s not unusual to find that the wind speed 20 inches above your crop canopy is 2 to 3 mph slower than a nearby airport’s reading."
-Dr. Bob Beck, Regional Agronomist at Land O'Lakes
Validation of current conditions meeting label requirements is every applicator’s priority and should be incorporated into all spraying application decisions. With the Kestrel 3550AG, you can easily monitor real-time weather conditions at the field-level.
Easy Record Keeping for Peace of Mind with the Free Kestrel App
As regulations surrounding drift management get tighter and media and public attention continues to increase, the stakes are higher than ever for applicators and farmers when it comes to accountability. It’s imperative to document spray conditions to defend against costly litigation and protect the future of your operation. The Kestrel app makes it easy to do by wirelessly connecting to the 3550 so you're able to view, log, and manage weather data on a mobile device. Now you can document field data right at the time of spray application -- forget pen and paper notes that can get lost or attempting to data log hours after the application when you’re back in the office and likely to forget. With just one click, the Snapshot feature in the app captures and saves an instant record of all live measurements along with a GPS-based timestamp. Conveniently export historical data as valuable documented evidence that you sprayed within acceptable weather conditions.
Pocket sized, rugged, waterproof, affordable, easy-to-use and equipped with on-unit data logging and wireless data retrieval for monitoring and reporting, the Kestrel 3550AG is your trusted weather guide for spraying and farming.
