Capillary tube of solid glass, bar-shaped, prismatic (optic enlargement of the column, except for high temperature types), diameter approx. 6 mm, oval opening, with yellow background for mercury* and white background for blue fluid column. Scale is deeply burnt in black, thus being absolutely resistant. The main graduations, which correspond with the printing on the casing, are especially clearly outlined.

Thermometric liquid

In the standard version from -30 to 250 °C blue thermometric fluid ("Fü"); for temperatures above 250 °C only mercury* is possible (short designation "Hg").
