4000 Pocket Weather Meter w/Bluetooth - Olive Drab
Part #: 0840BOLV

The Kestrel 4000 Pocket Weather Meter is the baseline wind and weather meter in the Kestrel 4000 series. What sets the 4000 series apart from the rest of the Kestrel family is that these high tech weather meters have the capability to store up to 2000 points of weather data, enabling you to track changes in the environment over time. This unique function opens up an entirely new realm of weather tracking capabilities for Kestrel Weather Meter users.

The Kestrel 4000 Pocket Weather Meter is the first in the next generation of Kestrel Meters. It has all the wind and weather monitoring functions available with the Kestrel 3500 Wind Meter, plus the distinct 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 Kestrel 4000’s display, and even upload the data to your PC or Mac with the Kestrel Interface. The Kestrel 4000 series is now available with Bluetooth Technology, which allows you to communicate with your Kestrel at a range of up to 30-feet, and maximize the battery life of your weather meter.

Each Bluetooth Meter includes custom communication software designed to quickly and easily configure your data transmission frequency, download logged data, graph data and transfer data to other applications. It is no longer necessary to purchase an interface separately, the new Kestrel Meters with Bluetooth include the software necessary to communicate wirelessly.

The advantage the Kestrel 4000 provides to scientists, athletes, firefighters, automotive technicians, and agricultural specialists is immeasurable. With Kestrel 4000 technology, you will not only know the current weather conditions, but be able to track changes in the environment and therefore make predictions as to what may happen next.

Included with the Kestrel Meter 4000 is: Soft Carry Pouch, Wrist & Neck Lanyard, 5 Year Warranty, 2 AAA Batteries & Kestrel Certificate of Conformity

4300 Construction Weather Meter - Safety Green
Part #: 0843

The Kestrel 4300 Construction Weather Tracker is the first Kestrel wind and weather meter designed specifically for construction professionals, especially those who work with concrete and other materials that require curing. The new evaporation rate function makes the Kestrel 4300 the ideal wind and weather meter for concrete contractors. In addition, the 4300’s long list of weather tracking capabilities* puts instant and accurate environmental data right in the palm of your hand. The Kestrel 4300, as well as the entire Kestrel 4000 series, is now available with Bluetooth Technology to transmit data wirelessly. The Kestrel 4300 Construction Weather Tracker has all the features of the Kestrel 4000, plus evaporation Rate (for measuring concrete moisture)

Before the introduction of the Kestrel 4300, concrete contractors would employ a Kestrel Meter to measure the surrounding conditions, then calculate the evaporation rate of a pour by referencing the American Concrete Institute chart. The Kestrel 4300 measures the evaporation rate of concrete automatically by calculating the temperature of the concrete (obtained with a thermometer or IR) with the relative humidity, ambient temperature, and wind speed.

The Kestrel 4300’s usefulness on a job site is hardly limited to measuring the evaporation rate of concrete or preventing plastic shrinkage: Wind speed functions are invaluable for crane operations; heat index keeps close tabs on working conditions; humidity measurement for paint and drywall; pressure trend can warn of impending storms; the list goes on.

Every 4000 series Kestrel Meter stores thousands of weather data points - tracking minimum, average, and maximum values - and graphs the trends for you.

The Kestrel Meter 4300 Construction Weather Meter includes a soft carry pouch, neck lanyard and 2 AAA batteries.

4500 Pocket Weather Meter Horus ATrag Ballistics - Olive Drab Night Vision
Part #: 0845HOLV

Kestrel Pocket Weather Meters and Horus Vision have partnered to provide a powerful shooting tool that combines the critical environmental data and targeting software solutions required for precision shooting -- all in one four-ounce pocket-sized unit. Previously, shooters would need to obtain environmental data from a Kestrel meter and then input that data into a PDA loaded with Horus ATrag ballistics software. Now, the Kestrel Ballistics Weather Tracker with Horus ATrag Software contains all of the necessary data and solutions in one device to minimize user workload and distraction. Plus, the Kestrel meter is IP67 waterproof and MIL-STD-810F rugged, allowing users to avoid the expense and weight of a ruggedized PDA.

The Kestrel 4500 NV with Horus ATrag Ballistics combines Kestrel’s flagship meter, the Kestrel 4500 with Night Vision, with Horus ATrag Ballistics software to bring you the first lightweight, hand-held tool to give you both comprehensive environmental data plus integrated aiming solutions. Kestrel Pocket Weather Meters and Horus Vision partnered to provide a powerful shooting tool that combines the critical environmental data and targeting software solutions required for precision shooting.

The Kestrel 4500 NV with Horus ATrag Ballistics allows you to load, customize and store multiple guns, rounds and targets. Target parameters include distance, angle, longitude, speed, direction and wind. Kestrel’s highly accurate measuring and averaging of wind together with built-in digital compass for target bearing and wind direction assists in defining the target winds.

The unit allows users to load and customize multiple guns and rounds from the extensive proprietary Horus database. Simple, intuitive screens allow the user to create up to five targets customized for location, distance, direction, declination and winds. The Kestrel meter’s highly accurate measuring and averaging of wind and digital compass for target bearing and wind direction assists in defining the target winds. Once these parameters are set, the Kestrel meter takes over - tracking the current met data and automatically updating the firing solution using Horus ATrag advanced proprietary algorithms and taking coriolis and spin drift into account. No additional user input is required.

Horus software that comes with the 4500 Atrag Ballistics is the civilian version. The military version of the Horus ATrag Ballistics software is only available via special GSA contract to officials with the correct security clearance. The software that ships with the Kestrel 4500 Horus ATrag is version 3.0. It is possible to upgrade the firmware as new versions become available, however it will need to be returned for firmware updates.

The Kestrel 4500 Horus ATrag Ballistics accurately measures/features:

• Active Targets & Target Range
  
• Wind Direction & Wind Speed
