Wind energy professionals who need assurance of exceptionally accurate wind-speed measurements can use the new Measnet Calibrated C3 anemometer from Second Wind, the only company to stock anemometers calibrated by a Measnet-certified facility.

Each of the new anemometers is calibrated at the Svend Ole Hansen ApS wind tunnel in Denmark, one of seven facilities in the world approved to calibrate to Measnet standards. Measnet, the Measuring Network of Wind Energy Institutes, is an international cooperative that serves the wind energy industry by working to ensure high-quality measurements, uniform interpretation of standards and interchangeable results. Member facilities provide calibration reports, take part in round-robin exercises where calibration results are compared to Measnet standards, and undergo third-party inspections.With this new option, Second Wind customers worldwide have three choices of three-cup anemometers:

• The new Measnet-calibrated model provides the ultimate assurance of wind-measurement accuracy. Previously, customers who need this assurance have had to place special orders or purchase the anemometer and send it to a Measnet facility.
• The Second Wind C3C anemometer, calibrated at the Massachusetts Institute of Technology's Wright Brothers wind tunnel, provides high standards of accuracy for most wind assessment applications.
• An uncalibrated C3 model provides a lower-cost option for less-demanding applications. Second Wind is the only U.S. manufacturer to offer an uncalibrated three-cup device.

The Measnet Calibrated C3 anemometer will be available later this month at a list price of US$ 375. The C3C model with standard calibration is priced at US$ 295, and the uncalibrated Model C3 is available for US$ 115. Second Wind will ship directly to customers in North America; customers in Europe and Asia can purchase from their Second Wind distributor.
