For years our customers have been asking for wind direction along with wind speed. New for 2007, the Kestrel 4500 does just that with its built in digital compass. But it doesn’t stop there.

The new Kestrel 4300 Construction Weather Tracker measures and displays evaporation rate — a function of relative humidity, temperature and wind speed. Evaporation rate is a critical environmental indicator that concrete contractors use to ensure they avoid plastic shrinkage cracks in concrete installations especially concrete flatwork..

The Kestrel 4200 makes HVAC technicians jobs even easier with automatic wet bulb temperature and humidity ratio readings. Of particular interest to dehumidification professionals, the Kestrel 4200 measures relative humidity, dewpoint, wet bulb temperature and heat stress index as well as the humidity ratio

In 2000, we introduced the Kestrel 4000 Pocket Weather Tracker, and today it is still the most comprehensive pocket weather meter on the market. For just under 4 ounces, you get every environmental reading with the press of a single button. The 4000 is unparalleled in its ease of use and totally customizable navigation and data display.

Many Kestrel users need to know everything that the weather is doing, but don’t need to log the data. We developed the Kestrel 3500 just for them. It provides comprehensive environmental data on nine different measurements with the simplicity of the Kestrel 1000.
