The thermometer is the name of the temperature measurement instrument.The temperature measurement instruments of the kerosene temperature meter are the temperature measurement instruments based on kerosene liquid as the carrier.The kerosene thermometer is a relatively stable temperature measurement instrument that can scientifically measure data. Like mercury thermometer, it is widely used in our daily life.
Kerosene temperature meter price
Callery thermometers are generally produced by different manufacturers, and the prices of different materials will be different.The price is about 10 yuan.
What should I do if the coal and oil temperature meter is broken
Since the thermometer of the kerosene is mostly fixed in one area, when fixed, it is necessary to use its dedicated fixing parts to fix it with the wall or temperature measurement area to avoid problems with fixed aspects and fall to the ground to the ground.Create it to shatter.Even if the instrument of this kind of kerosene thermometer is accidentally broken, as long as it is not fell to its temperature -measured part, it can be continued to be used. It is only necessary to be careful during the use process to prevent glass fragments or the edges and corners parts.There are scratches for users, but when they meet this situation, the author suggested that customers can buy one again.When it comes to how to do such a problem when the kerosene thermometer is broken, the author recommends that users can choose to buy a new temperature measuring instrument.This is mainly because the price of this temperature meter is relatively affordable. Generally, from a few dollars to dozens of dollars, customers can re -select a temperature measuring instrument that suits them according to their preferences or use where the purpose is located.Do not cause a big disaster to save a few dollars.
Principles of kerosene thermometer
The kerosene thermometer is composed of three parts: glass bubble, glass tube and scale.The coal thermometer is basically the same as the principle of other liquid thermometers, that is, a certain working liquid is installed in the sealed glass bubble. When the temperature is measured, the liquid in the glass bubbles is hot and cold shrinks, resulting in the inner liquid in the glass tube.As the surface rises and falls, the corresponding scale corresponds to the final liquid surface is the instant temperature.
Coal oil thermometer use
First understand the measurement range of the three commonly used thermometers: the working substance of the kerosene thermometer is kerosene. Its boiling point is generally higher than 150 ° C, and the solidarity point is lower than -30 ° C. So the amount range of the kerosemeter thermometer is about -30 ℃ ～ 150 ℃.Because the boiling point of alcohol is 78 ° C, the solidification point is -117 ° C, the alcohol thermometer can test a lower temperature than the kerosene thermometer, but the temperature higher than 78 ° C cannot be determined.Compared with the mercury thermometer, neither of the latter two are poisonous. Compared with alcohol thermometers, the kerosene thermometer can measure the temperature higher than 78 ° C. There are some benefits in use: 1. The first is that the kerosene thermometer is easy to observe. They are generally bothThe instructions of the big red. 2. The second is relatively safe. If it is crushed in the fish tank, it can float on the water surface if it is broken due to the low oil density than the water density than the water density.
Meeting of kerosene temperature
I. The measurement range of the kerosene thermometer is: -30 degrees Celsius to 150 degrees Celsius (the working material of the kerosene thermometer is kerosene, its boiling point is generally higher than 150 ° C, and the solidaries are lower than -30 ° C. 2. The maximum range of alcohol thermometer is:-117 degrees Celsius to 78 degrees Celsius (the boiling point of alcohol is 78 ° C, and the solidarity point is -114 ° C) 3. The measurement range of the carbon nanometer thermometer is: 18 degrees Celsius to 490 degrees Celsius. Four. The measuring range of mercury thermometer: 0 degrees Celsius to 400 degrees Celsius.Frequent application: (1) The range of the cold and summer table is generally: -30 ℃ ～ 50 ℃.(2) The range of thermometer for experiment: -20 ℃ ～ 110 ℃. (3) The range of the thermometer is 35 ℃ ～ 42 ℃ (the thermometer is measured by the bodys body temperature, the limit range of the human body temperature changes is between 35 and 42 degrees Celsius)
