Wind Speed & Direction Merlin Wireless Wi-Fi
Cat. No. I-WSDMW
Weight 2 lbs

This wireless version of the popular Merlin wind speed instrument records changes, trends and present wind conditions.  Digital readings are given in four modes: 'Present' displays existing wind conditions; 'Peak' gives speed and direction of highest gust since last reset; 'Average' reveals average wind speed and direction since last reset; and 'Forecast' compares the most recent 12-minute average with the previous 12 minutes.  

Features user-selectable units of measurement for wind speed (MPH, Knots, km/h or m/s).  Wind direction is displayed via eight LEDs over a 16-point compass rose pattern.  Merlin can interface with Mystic to compute wind chill readings.  Memory data is protected by a 10-year internal back-up system.  

Includes AC adapter, wind speed & direction sensors, solar powered wireless transmitter with rechargeable NiCad batteries, and mounting hardware.   

NOTE:  A single 900mhz Wireless Receiver (sold separately) is required to operate this system.
