What is the Difference Between Thermometry and Thermography?

The main difference between thermometry and thermography lies in the way they measure temperature and the areas they cover. Here are the key differences:

• Thermometry: This technique involves the measurement of the temperature of an object using devices such as thermometers or pyrometers. It is used to determine the temperature of a specific spot or location on an object. Thermometers and pyrometers can only measure one spot at a time, which may take longer to find a hotspot or other fault.
• Thermography: This technique describes the measurement of abnormally hot or cold areas on an object. It uses thermal imaging cameras to detect infrared radiation and translate it into a temperature reading. Thermal cameras have several advantages compared to traditional thermometers, such as being able to accurately measure temperatures from larger distances and covering a wider area.

In summary, thermometry focuses on measuring the temperature of a specific spot, while thermography measures abnormally hot or cold areas on an object and covers a wider area. Both techniques are important measurement tools in chemistry and have various applications in different fields, including medicine, veterinary medicine, and analytical chemistry.

Both thermometry and thermography are important measurement techniques in chemistry and have applications in various fields, including analytical chemistry. Thermometry focuses on measuring the temperature of an object, while thermography is concerned with identifying abnormally hot or cold areas on an object's surface.
