Description

The 4000 Pocket Weather Tracker is the most comprehensive pocket weather meter on the market. It measures barometric pressure, altitude, humidity, heat stress, dewpoint, wet bulb temperature, density altitude, wind speed and much more. The Kestrel 4000 is unparalleled in its ease of use, you get every environmental reading with the press of a single button. The Kestrel 4000 is an extremely durable meter that has been put to the test in the harshest conditions, it has been subjected to impact, water submersion and extreme temperatures, and keeps on working.

In addition to measuring the current wind and weather conditions, the Kestrel 4000 has the advantage of data storage, graphing functions, and computer interface technology. With these additional options you will be able to record changes in the weather over time, view these changes as graphs on your 4000's display, and even upload the data to your PC.

The 4000 has a night-vision preserving backlight option which helps users to sustain natural night vision. NV backlights are also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations.

All Kestrel instruments are made in the USA and are backed with a Five-Year Warranty.
