The common contact measuring tool is thermometer, and the non-contact measuring includes infrared thermometer. Thermometer is a common tool to measure the temperature of an object. It measures the temperature by contacting with the measured object and using the principle of thermal expansion and cold contraction of the substance. When using a thermometer to measure the temperature of an object, we should pay attention to selecting a suitable thermometer, keeping the thermometer in full contact with the measured object, and reading the thermometer correctly to ensure the accuracy of the measurement results.
In addition to thermometer, infrared thermometer is also a commonly used non-contact tool to measure the temperature of objects. It determines the temperature of an object by measuring the infrared energy radiated from the surface of the object, which has the advantages of rapidity, accuracy and non-contact, and is widely used in various fields.
No matter which measurement method is adopted, it is necessary to choose the appropriate measuring tool according to the type and temperature range of the measured object to ensure the accuracy and reliability of the measurement results. At the same time, when using measuring tools, it is also necessary to operate in strict accordance with the instructions to avoid errors and safety problems.
The function of thermometer:
Thermometer is an instrument for measuring temperature, and its main function is to measure the temperature of objects, which provides important support and guarantee for work and life in various fields. By measuring temperature, people can better understand and control various physical and chemical processes, ensure the quality and safety of products, and protect human health and environmental safety.
Thermometer is one of the indispensable tools in scientific experiments. Scientists need it to measure the temperature change during the experiment to ensure the accuracy and reliability of the experiment. In the medical and health field, doctors need to measure patients' body temperature with the help of a thermometer to determine their health status and diagnose diseases. In industrial and agricultural production, thermometers are also widely used to monitor the temperature in the production process to ensure product quality and production efficiency.
In addition, thermometers are widely used in daily life. For example, thermometers and thermometers commonly used at home use the principle of thermometers to measure indoor temperature and human body temperature. Through these thermometers, people can better master their living environment and maintain a healthy and comfortable life.
