Designed specifically for agricultural professionals that spray crops, the Kestrel 3500 Delta T Weather Meter provides several agriculture specific measurements including the Delta T. Delta T is the spread between the wet bulb temperature and the dry bulb temperature, offering a quick guide to determining acceptable spraying conditions. When you know Delta T, you ensure that every drop of spray counts and that you are staying within spraying regulations.

Designed with the farming community in mind, the Kestrel 3500 Delta T is effective in many agriculture specific measurements, but does not measure wind chill or heat stress index like its close cousin, the Kestrel 3500. The easy to use menu system quickly scrolls through all environmental measurement conditions. The Kestrel 3500 Delta T has an external temperature sensor with a waterproof casing that allows you to gauge the temperature of water, snow, and the open air. The sensitive and user-replaceable impeller provides accurate wind speed info. A hard slide-on case, lanyard, and battery are included.
