Accuracy : 0.5 m.s-1
Threshold : 0.2 m.s-1
 
 



WIND VANE

Designed for recording wind directions.
 

MEASUREMENT SPECIFICATIONS

The vane should be installed in such a way that it indicates the direction from where the wind is blowing.
 

TECHNICAL SPECIFICATIONS

Scale : O to 360
Accuracy : 5°
Threshold : 0.5

Frequency of chart record (indicate on order) :
- drum recorder : daily, weekly,
- strip chart : 2 weeks to monthly or more (paper speed selectable from 10 to 20mm/h)
