VTR-100

Visual Tube Rater

Test Methods
ASTM D3241, IP 323

 

The Alcor VTR-100 (Visual Tube Rater) is used to manually rate heater tube deposits formed during a jet fuel thermal oxidation test.

The heater tube is attached to a holder and inserted in the VTR-100, along with the ASTM Color Standard (included). The tube holder may be moved up and down and rotated to locate the darkest section of the tube; the color codes on the ASTM Color Standard may be moved adjacent to the section of the tube being rated. Both are illuminated by special lights and are easily observed through an attached viewer.
