Details for several types of Wind/Meteo Loggers & Servers:

 Wind logger kit BASIC 
For general purposes 

For STANDARD LOW COST Applications choose windlogger kit BASIC 
with 6410 anemometer
A high quality cost effective set for logging average wind speed and direction
during eg 10 minutes interval (or any other adjustable interval) 
(Optional also with minimum, maximum and turbulence intensity)
For  Surfing & Sailing, Small Windturbines, simple wind monitoring, environment, air pollution, education etc.
Accuracy: 6410 anemometer: 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)
                   low cost anemometer 6410

 Wind logger kit PLUS

For INDUSTRIAL  Applications choose windlogger kit PLUS
If higher accuracy and reliability is required choose Wind Logger kit PLUS

For accurate and reliable recording average wind speed only 
Can be used for general industrial use and small wind energy projects (kW).

PROFESSIONAL Windlogger for BIG wind energy projects (MWatts)

For EXPERT applications:  
If  higher accuracy is required  (up to 0.1 m/s with optional calibration certificate)
and recording of more anemometers (up to 8)  average, maximum,
minimum and standard deviation (for determination of turbulence intensity)
then choose our advanced 
Professional Windlogger, which is used for
site analysis & evaluation of big wind energy projects (MegaWatt Class). 

We supply customized configurations for this windlogger including First Class
Sensors (anemometers en vanes) and including atmospheric pressure sensor,
temperature sensor(s) and other required inputs and sensors
(extra acoustic wind sensors, counters, status inputs, alarm outputs etc.) and also
3G Router and online Graphs. 

Our customers are using this windlogger for projects with mast up to 125 meter
and usual 4-6 First Class anemometers.  Ask a quote for your project!

Our professional windloggers are equiped with a highly accurate (1sec) running
average filter and 16 bits AD conversion (resolution of 0.01 m/s)  and have low
power consumption.

Optional MEASNET Calibrtaion certificate (IEC61400-12).
