ULTIMETER 2100 Weather Station (with 100-ft. wind sensor cable) Peet Bros. ULTIMETER 2100 is the ultimate electronic weather station for the professional or serious amateur weather observer. Measures WIND SPEED, WIND DIRECTION, BAROMETER, OUTDOOR TEMPERATURE, INDOOR TEMPERATURE, WIND CHILL, TIME, DATE, OUTDOOR HUMIDITY (with optional sensor), DEW POINT, AND HEAT INDEX; INDOOR HUMIDITY (with optional sensor), and RAINFALL (with optional sensor). And it offers the unsurpassed performance and reliability of cabled sensors - the professional's choice. The included ULTIMETER PRO Anemometer provides exceptional response in all wind conditions, including very low wind speeds (typical starting threshold 1.5 mph!) Unlike conventional wind sensors, its patented all-digital design has no potentiometer or other friction contacts to wear out. It features corrosion-proof bearings with self-lubricating Delrin races and surgical steel balls. The UV-resistant polycarbonate housing will resist the harshest elements for many years. The system has an exclusive 9-BANK MEMORY SYSTEM for highs and lows: today's, each of the previous 7 days', and long-term. After a major storm, you can save all the interesting extreme values to show friends weeks later, yet still display all of today's readings. You'll also see the exact time and date every high and low occurred. You can reset memories individually, or use MASTER RESET to clear all. This makes it easy to keep monthly records or to monitor the highs and lows while you are away.
