80 years GRAW Radiosondes – our subsidiary is celebrating anniversary!

Especially in connection with such an event, it is common to release balloons. This is exactly what GRAW is doing day by day – but the balloons are equipped with radiosondes. With such radiosondes and other measuring instruments, GRAW is one of the leading manufacturers of meteorological instruments for the last 80 years – enough for us to look back at the eventful past of our company.
