For professionals and weekend campers, sailors and outdoor enthusiasts, the Kestrel 4000 can literally become a lifesaver. It is considered one of the most accurate and extensive models of weather monitors on the market today. Although it only measures within the size of the palm of the hand, it can measure wind speed, dew point, heat index, barometric pressure, altitude, temperature, humidity, wind chill, wet bulb, and density altitude with a few hits of a few buttons.

The Kestrel 4000 weighs about 102 grams (3.6 ounces) and measures 12.7 by 4.5 by 2.8 centimeters (roughly five by 1.8 by 1.1 inches). It can be kept swinging from the wrist or neck by a secure lanyard and can be purchased with a rough weather pouch to protect it from rain, snow and extreme conditions. It is completely waterproof and can float if dropped overboard.

The unit can measure, store and chart at least 250 measurements and reveal them on an easy to read backlit liquid crystal display. Users can create customized screens to gauge "commonly measured" parameters at the touch of a button. All of these measurements are stored on the internal memory chip, even when the machine is powered down.

Professional Uses of the Kestrel 4000

Many businesses and industrial agencies utilize Kestrel instruments to gather important weather information for a number of applications. Many people use the Kestrel 4000 unit, including campers, winter athletes, military personnel, crop dusters and agricultural industries, educational researchers, sailors and boating enthusiasts, and HVAC (ventilation) experts. Whether homeowners or survivalists use it, the 4000 model seems to be able to handle any measurement challenge for personal and professional use.
