Laboratory Vane Apparatus
The laboratory vane apparatus is based on an original concept of the Transport and Road Research Laboratory of the United Kingdom. It offers versatility with a variety of vane sizes available. Typically it comes with the standard 12.7 mm square vane along with a set of four calibrated springs. Testing can be conducted either directly on the sample or within the sampling tube. For the latter, the NG-WF1738 Attachment for 38 and 100 mm diameter sampling tubes is recommended for optimal performance.
