Glass rod thermometer features and USES

Glass rod thermometer by equipped with liquid glass package thermal capillary and scale and security package of five parts. When the thermometer is placed in the measured medium, when heated temperature package thermal fluid, volume expansion, thermal fluid in capillary height along with the different of the measured temperature changes, which can be read on the scale of measured temperature value. Glass thermometer is the use of the principle of heat bilges cold shrink to realize the measurement of temperature, load thermal fluid in the glass heat package. Liquid temperature, thermal expansion, the expansion coefficient of liquid is greater than the glass, as a result, the thermal fluid along the capillary rise, thus learned heat from the liquid column height in capillary liquid temperature. Glass rod thermometer according to the classification of shape: straight, right Angle type, 135, Angle. Glass rod thermometer to points: according to the use of mercury, organic liquid ( The red and blue) Mercury measurement range for - 30 ℃ ~ 500 ℃ organic liquid measurement range of 100 ℃ ~ 200 ℃. Glass rod diameter 2 ￠. 5 ~ ￠14, length of 100 ~ 4000 mm, glass rod background to white and yellow. Glass rod thermometer need attention when using; 吗? In accordance with the provisions, immersion depth of measurement, in order to protect accurate temperature measurement,? Don't be shocked and backwards, in case of liquid mercury or alcohol off failure? No more than the highest when using, avoid explosion. Glass rod thermometer is widely applied to chemical, pharmaceutical, brewing, printing and dyeing and machinery manufacturing and at the same time can also be applied to all kinds of scientific research, education, medical laboratory, laboratory temperature measurement.
