  • We calibrate wind-speed and wind-direction!

    By on June 26, 2020

    Added to our calibration capabilities: calibration certificate on wind-direction. As we receive more and more request for not only wind-speed calibration but also for a calibration certificate on wind-direction, we have invested in this possibility. We can generate several calibration reports as a standard: starting from a 4 point calibration (per 90°), up to a 24 points calibration (per...
