Factory-reconditioned ULTIMETER^®100, ULTIMETER^®800, and ULTIMETER^®2100 Weather Stations! 

ULTIMETER 100 is a great basic weather station with remarkable capabilities, at a remarkably low price (rain gauge optional); ULTIMETER 800 adds relative humidity and dew point data (with optional humidity sensor), and ULTIMETER 2100 is the best in its class, with barometric pressure features included.  The much-anticipated successor to our most popular weather station ever (the ULTIMETER 2000, world-renowned standard for performance and reliability in a home weather station), the ULTIMETER 2100 features a stunning platinum-tone housing with brilliant blue display backlighting.  To improve the user interface still further, an illuminated keypad provides exceptional visibility in darkness or low-light conditions (ULTIMETER 800 also). The factory-reconditioned ULTIMETER 100, 800, and 2100 utilize Peet Bros.' patented and proven weather sensor technology, including our unique all-digital wind sensor, 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).  They also features direct serial data output including WeatherText®, and are APRS-ready.  And they offer the unsurpassed performance and reliability of cabled sensors - the professional's choice (see Why are cabled sensors better?)  Factory-reconditioned ULTIMETER Weather Stations come with the same 1-year warranty as our new weather stations.
