Calibration wind tunnel 2 (PTB)
This wind tunnel serves the German national metrology institute (Physikalisch-Technische Bundesanstalt – PTB) as a comparison and reference channel for the unit "m/s". In other words: In this wind tunnel, a PTB transfer standard is installed to represent the physical unit "meters per second" for air flows. In addition, PTB regularly conducts comparison measurements for national and international interlaboratory comparisons.
