Final answer:
A temperature measuring device used during the transport of food shipments is a thermometer, which measures temperatures using scales like Fahrenheit, Celsius, and Kelvin.
Step-by-step explanation:
A temperature measuring device that is attached to a shipment of food to monitor temperatures during transport is called a thermometer. Thermometers are essential tools used to measure temperature through various means, such as alcohol, liquid crystal, and infrared radiation (pyrometer). They adhere to well-established temperature scales, including Fahrenheit, Celsius, and Kelvin. These scales utilize pre-defined reference points like the freezing and boiling temperatures of water. The importance of thermometers in food safety is highlighted as they ensure food reaches a temperature high enough to kill any bacteria. Moreover, modern versions, such as infrared thermometers, provide quick and accurate readings and are utilized in various settings, including healthcare and industrial environments.
