Key Features of Industrial Glass Thermometers

• The ranges are from -60°C to 600°C [in different ranges] with an accuracy of 1%.
• The capillary tube made of solid glass, bar-shaped, prismatic [optic enlargement of the column], oval opening, with yellow background for mercury and white background for blue-lid column.
• Calibration is deeply burnt, in black, thus being absolutely resistant.
• The main graduations, which correspond with the printing on the casing, are especially clearly outlined.
• Tubes are manufactured of brass for temperature up to 300°C & for more than 300°C will be in stainless steel.
• The process/thread connections are also available in various types.
