About Kestrel 3500

The Kestrel 3500 Waterproof Yellow Weather Meter/Digital Psychrometer has the most functions of any Kestrel Meter in the 3000 series. The Kestrel 3500 measures temperature, wind speeds, barometric phenomena, pressure trends of up to 3 hours and more. The Kestrel 3500 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. For those who need a full reading of only the latest weather information, the 3500 is the ideal Kestrel Meter.

In addition to the Kestrel 3500's pressure trend indicator, it also has the advantage of altitude and barometric pressure measurement. With these features on hand at any time, the Kestrel 3500 becomes an ideal weather instrument for outdoor enthusiasts, sportsmen and women and anyone else that will benefit from accurate and up to the second weather and barometric information.

The Barometric Trend feature is not quite the graph of the Kestrel 4000 series, but rather an arrow indicator. The arrow will indicate the trend of the previous 3 hours even if the meter was off. If the batteries are changed, the arrow will show just the current trend, not historical.

The Kestrel 3500's easy to use menu system scrolls through 9 different 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.
