What should refrigeration units have for monitoring temperature?

Refrigeration units should be equipped with a numerically scaled thermometer to effectively monitor temperature. This type of thermometer provides a clear and precise reading of the unit's internal temperature, enabling food handlers to ensure that food is stored at safe temperatures to prevent bacterial growth and foodborne illnesses.

Having a numerically scaled thermometer is crucial for proper temperature regulation, as it allows staff to easily interpret the readings and make necessary adjustments to the refrigeration unit if the temperature deviates from the safe range. This not only aids in compliance with health regulations but also promotes food safety in any establishment that handles perishable goods.

While a digital thermometer can also give accurate readings, the emphasis on a numerically scaled thermometer reflects the importance of using a device that can be read at a glance without the potential complications or electronic failures that might occur with digital equipment. Non-scaled thermometers and the notion of having no thermometer do not meet the standard requirements for monitoring critical food storage temperatures effectively.
