Our Review of the Kestrel 3500 Delta T meter

All Kestrel Pocket Weather Meters are made in the USA and covered by a 5-year warranty against manufacturing defects. Additionally, every single Kestrel manufactured is calibrated for every single value, either directly against NIST-traceable standards or against an intermediary standard that is calibrated daily. Every unit is shipped with a FREE Certificate of Conformity that states what calibrations were performed, and the certified performance specifications.

Designed specifically for agricultural professionals, the Kestrel 3500 Delta T provides Delta T readings. Delta T is the spread between the wet bulb temperature and the dry bulb temperature, and it offers a quick guide to determining acceptable spraying conditions. When you know Delta T, you ensure that every drop of spray counts.

In addition to calculating Delta T, the Kestrel 3500 Delta T also provides the same critical data available on the Kestrel 3500 Wind Meter. The only features available on the 3500 that are not available on the 3500 Delta T are wind chill and heat stress index.

The Kestrel 3500 Delta T measures temperature, wind speeds, barometric phenomena, and more. The Kestrel 3500 Delta T provides a complete range of weather measurements, but does not log accumulated data like the more high-tech weather meters of the Kestrel 4000 series.

In addition to the Kestrel 3500 Delta T's unique agricultural calculations, it also has the advantage of altitude and barometric pressure measurement. With these features on hand at any time, the Kestrel 3500 Delta T becomes an ideal weather instrument.

The Kestrel 3500 Delta T's easy to use menu system scrolls through each of its environmental measurement conditions. It 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 technology provides accurate wind speed info, and a hard slide-on case, lanyard, and battery are included.

The Kestrel 3500 Delta T accurately measures:

Air, Water and Snow Temperature
Altitude
Average Wind Speed
Barometric Pressure
3- hour pressure trends
Current Wind Speed
Delta T
Dewpoint
Maximum Wind Gust
Relative Humidity
Wet Bulb Temperature

We Also Recommend:

If you do not need the specific Delta T calculation, the Kestrel 3500 Wind Meter trades Delta T for measurements of wind chill and heat stress index.
