Final answer:
Thermocouple thermometers with immersion probes are used to measure the temperature of liquids, meat, surfaces, and storage units.
Step-by-step explanation:
Thermocouple thermometers with immersion probes are used to measure the temperature of liquids, meat, surfaces, and storage units. They utilize the principle of thermoelectric effect, where a temperature difference between two dissimilar metals generates an electrical voltage. This voltage is then used to measure the temperature accurately.
