Peet Bros. Company, Inc.

ULTIMETER® Anemometer/Wind Vane, "PRO" model (for original replacement or special application). Included with all models ULTIMETER weather stations manufactured in 2006 or later (how to check for compatibility). Supplied with 4-conductor 40 ft. cable. 2.6 inch diameter wind cups. Cable lengths longer than 250 ft. available by special order. The ULTIMETER PRO Anemometer/Wind Vane features exceptional response in all wind conditions, including very low wind speeds (typical starting threshold 1.5 mph! here's why). Unlike conventional wind sensors, our patented digital design has no potentiometer or other friction contacts to wear out. It features bearings that are virtually corrosion proof, with self-lubricating Delrin® races and surgical steel balls. The precision-molded housing of UV-resistant Lexan® will resist the harshest elements for many years.

ULTIMETER 100 uses the same top-quality sensors, including the incomparable ULTIMETER PRO Anemometer, featuring exceptional response in all wind conditions, including very low wind speeds (typical starting threshold 1.5 mph! here's why). It also uses the same great data processing as our renowned 2100 system, including WeatherText® serial data output, and is APRS-ready. A second Serial Data Port connection (new feature) is provided in the ULTIMETER 100's sensor junction box, delivering greater flexibility in the location and connection of The Weather Picture (an optional wall-mounted display), PC Weather Data Logger, or other peripheral weather accessory. And it offers the unsurpassed performance and reliability of cabled sensors - the professional's choice (see Why are cabled sensors better?). It is unsurpassed as a basic electronic weather station for the professional or serious amateur weather observer.
