While the SSWA strives for maximum accuracy, this station has not been calibrated with laboratory-grade reference equipment and therefore is not certified for research-grade measurements.
We continuously maintain and upgrade sensors to improve accuracy, but we do not provide laboratory-traceable uncertainty measurements.
