V-Line Glass Thermometers

The sealed glass capillary contains a small bulb filled with a liquid or mercury. This fluid will expand with the application of temperature and will rise into the capillary. A scale is fixed in a corresponding position next to the capillary. The divisions are etched on to the glass itself and the scale is printed on to the corresponding “V” formed aluminium housing. The assembly of the thermometer is practical and resistant to breakage if correctly installed.
