The NRG Class 1 anemometer is the ideal, low-cost solution for wind resource assessment projects that require an anemometer with class 1A compliance.
The NRG Class 1 Anemometer is a ball-bearing version of our industry-leading NRG 40C Anemometer. That is, it relies upon the same compact external form factor for easy transport and installation. Inside, the patented dual shaft design of the NRG Class 1 protects the bearings from debris and the common impact loads experienced in harsh climates, while the bearings themselves deliver the low friction necessary to achieve certified class 1 performance.
NRG was the first company to obtain endorsement in the classification of an anemometer from Troels Pedersen of the DTU Wind Energy Department. A MEASNET calibration certificate comes with each sensor.
