Science and technology are developing more and more, and human temperature measurement technology has been continuously developed and improved, so there are more and more thermometer specifications . Have you seen the thermometer specification model ? Let's take a look at the differences between the thermometer specifications and models .
1, the specification of the thermometer model
A thermometer is a general term for all tools that measure temperature. It can accurately measure and judge temperature. Certain properties of all matter change as the temperature changes. Thermometer specifications are available in a variety of models . However, different thermometer specifications and working principles are also different. The temperature thermometer uses gas as a substance for measuring temperature, and its accuracy is high, enabling more precise temperature measurement. Resistance thermometers are manufactured based on changes in temperature and metal resistance. They measure from 260 degrees Celsius to 600 degrees Celsius and are used in a wide range of applications.
High-temperature thermometer A thermometer designed to measure more than 500 degrees Celsius. Although its principle and structure are relatively impetuous, its measurement range is wider than that of resistance thermometer. It can measure items from 500 degrees Celsius to 3000 degrees Celsius and cannot measure low temperature items. .
Different thermometer specifications include: internal standard, stick type, and depending on whether the electric contact is adjustable or not, the shape is also one of the indicators of different models of the thermometer. The range of temperature measurement of thermometers is also very different. Just like the thermometers listed in our appeal, their measurement range varies widely, and if the same thermometers are different in size, they can measure different ranges.
2, the use of thermometers
Do not select a useless thermometer that is out of range. Wait until the thermometer's display is stable before reading, and you can't read when the temperature is still fluctuating, which will cause the reading to be inaccurate. The thermometer cannot leave the object under reading, otherwise it will produce unnecessary errors. When reading, the eye should be a normal thermometer. The line of sight should be at the lowest point of the liquid surface of the mercury thermometer. Such a reading is a good reading.
Thermometers are very common in life. We understand that the thermometer specifications and thermometers should be used in the course of use, you can choose the thermometer that suits us, and use the thermometer correctly.
