Kestrel Meter 4500 Weather Meter

The Kestrel 4500 Pocket Weather Tracker is Kestrel's flagship meter series. Capable of monitoring and reporting an exhaustive list of environmental parameters – from temperature to barometric pressure, dewpoint, wind chill, and more, the Kestrel 4500 is feature-rich pocket weather meter. They are the top choice with military professionals, HAZMAT teams, and flight crews.

The NV versions of the Kestrel 4500 features a night-vision preserving backlight. The backlight incorporates optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision.  (Note: This backlight appears soft greyish pink, not "red", and is still in the visible spectrum, so is not compatible with night-vision equipment.)  The NV light is designed for optimal performance in low-light conditions.

Weekend shooters and military snipers alike have been calling for a Kestrel Meter with density altitude and crosswind calculation for years — and the Kestrel 4500 meets that demand completely.

If you select the Bluetooth model, your 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 at a range of up to 30-feet.
