APPLICATION
With its logarithmic scale, the 5 StVL combines the advantages of precision variometer with those of a standard variometer.
In the precision range from 0 to ±1 metre/second, the graduations are equal to 0,1 metre / second. From ± 1 metres‑/‑second to the end of the scale, the instrument is a standard variometer. Particularly suitable for ballooning.
