Duplex Roll Chart Recorder

Duplex Roll Chart Recorder

The duplex roll chart recorder is used to display and record the wind direction and the wind speed measured by the anemometer. Although the wind signals can be digitized to display on a computer monitor, the chart recorder can display the analogue wind signals in  continuous trace forms on a chart for easily monitoring gusty winds or the veering and backing of wind direction.
