What is the origin of the thermometer?

　　Santorini is considered the inventor of the thermometer because he published the earliest thermometer record in 1612. Gabriel Fahrenheit invented the first mercury thermometer in 1714. Infrared energy in the 1800s. Herschel knew that sunlight was made up of all the colors of the spectrum, so he wanted to explore these colors and their relationship with heat. He designed an experiment that used a prism to spread light into the color spectrum and used a blackened light bulb to measure a thermometer to measure the temperature of different colors. Herschel observed that the temperature rose from violet to red, and observed that the hottest temperature actually exceeded red light. Herschel called the heat caused by radiation that exceeds the visible red range "heat generation." Today, it is called "infrared" energy. Over time, many versions were created, until today the infrared version of high-temperature polymers exists.

　　How does the thermometer work?

　　An infrared thermometer measures the temperature from a distance. The range of this distance can be between miles or fractions of an inch. Pressure gauge factory infrared thermometers are usually used when other types of thermometers are not practical. For example, if the object is very fragile or close to danger, an infrared thermometer is a good way to get the temperature from a safe distance. Infrared thermometers work based on a phenomenon called black body radiation. Anything with a temperature higher than absolute zero will cause the molecules in it to move around. The higher the temperature, the faster the molecules move. As they move, the molecules emit infrared radiation, which is electromagnetic radiation below the visible light spectrum. When they get hot, they emit more infrared light and even start to emit visible light. Therefore, the heated metal will emit red or even white light. Infrared thermometers detect and measure this radiation. Infrared light works like visible light, it can be focused, reflected, or absorbed. Infrared thermometers usually use a lens to focus infrared light from an object onto a detector called a thermopile. The thermopile absorbs infrared radiation and converts it into heat. The more infrared energy, the hotter the thermopile becomes. This heat is converted into electricity. The electrical energy is sent to the detector, which uses it to determine the temperature at which the thermometer is pointed. The more electricity, the hotter the object. The thermopile absorbs infrared radiation and converts it into heat. The more infrared energy, the hotter the thermopile becomes. This heat is converted into electricity. The electrical energy is sent to the detector, which uses it to determine the temperature at which the thermometer is pointed. The more electricity, the hotter the object. The thermopile absorbs infrared radiation and converts it into heat. The more infrared energy, the hotter the thermopile becomes. This heat is converted into electricity. The electrical energy is sent to the detector, which uses it to determine the temperature pointed to by the Pressure type thermometer. The more electricity, the hotter the object.
