  A-1 Wind logger kit A1  For general purposes 
    LOW COST Windlogger with EKO21N datalogger for speed & direction:

   Type:  Windkit-A-EKO21-LC                    
   Buy online : 495 euro ex VAT   
     
   A high quality cost effective set for logging average wind speed and direction
   during eg 10 minutes interval and (optional) Beaufort number
  SPECIFICATIONS:
   Applications: 
   Surfing & Sailing, Small Windturbines, simple wind monitoring, environment, air pollution, education etc.
   Power requirements & possibilities: 
   3.5 V Lithium battery/5-10 Volts /8-14 V / 24 V DC @ current appr 80uA.  (specify at order)
   Accuracy: appr. 0,5 m/s (1-10 m/s) and appr 5% if speed > 10 m/s (eg at 20 m/s accuracy: 1m/s)
   This accuracy is OK for "non critical" wind measurements, but is insufficient for advanced &
   accurate wind energy research, see also know how about wind measurements for wind energy
   applications:  this is our specialty since 1983 and has been exported to over 90 countries.
   If higher accuracy is required choose Wind Logger kit B (accuracy typ 0.20 m/s if speed >0.5 m/s)
   or our professional windlogger (accuracy 0.2 up to 0.1 m/s), which can be supplied according your
   requirements, also with calibration certificates and First Class anemometers!
