Introduction of glass thermometer

Glass thermometer is a kind of artificial fire, priming and other process, low cost, measurement accurate, easy to use, no power of traditional temperature measurement products. Widely used in the production and life. With round or triangular rods glass as raw materials, with mercury or organic solution, Kerosene, alcohol, etc. ) As a thermal fluid, create suitable for the different needs of various products. Distinguish from the method of use, can be divided into full immersion type thermometer draw immersion type two kinds of thermometer, full immersion in measuring liquid thermometer need all glass thermometer in the measured object, bureau of immersion into the specified location shown on the thermometer only; Graduated from surface form and scale can be divided into the degree of acid etching and screen printing, corrosion degree of the acid etching is a sculpture technology, the scale value written in the book of the glass rod, silk screen calibration using silk screen printing process will be digital line graphics printed on the glass, and then after heat treatment to form the reddish brown and black color glaze effect, oil resistant to acid and alkali corrosion, not faded, never wear. Glass rod thermometer is usually straight, can also according to customer need to make a variety of angles. With the thermal fluid of organic liquid glass thermometer can measure - 100 ~ + 200 ℃ temperature, and mercury thermometer can measure - 30 ~ + 600 ℃ temperature.
