Historical information

Used on Gabo Island to measure maximun gust over previous 3 hours or between weather observations. Information on the back of the device implies that it was battery powered and indicates that it was used in conjunction with a Synchrotac brand anemometer. Its particular function was to measure maximum wind speed over three hours between weather observations. Like the other weather recording instruments in the collection, it became redundant to the Bureau of Meteorology’s needs.


It is a good example of its kind and has first level contributory significance for its historic value and provenance to the lightstation.
