Accessories for Kestrel Weather Meters

Kestrel Interface

With the addition of the Kestrel Interface, any Kestrel 4000 series meter becomes a complete weather station and data logger. Data can be uploaded for long-term storage, in-depth analysis and detailed charting. It also has a tripod mount, allowing the Kestrel to be mounted for continuous data logging.

Simply connect the interface cable to your computer, rest the Kestrel on the cradle, and upload your stored data. The included software is easy to use, and saves the data in a comma delimited text file for use in a text editor, spreadsheet or database.

The provided software works with PC (Windows 3.0 or higher). The interface is available with either an RS-232 9-pin serial connector or a USB connector.
