What quality does a thermometer used in a pasteurization unit have to meet?

A thermometer used in a pasteurization unit must be accurate within 1 degree to ensure precise monitoring of temperatures during the pasteurization process. This level of accuracy is crucial because pasteurization relies on reaching and maintaining specific temperatures to effectively kill pathogenic microorganisms without significantly affecting the quality of the product. If the thermometer is not accurate, it can lead to under-processing or over-processing, both of which can pose health risks or compromise product quality.

Maintaining this level of precision is particularly important in a regulated environment such as food processing, where compliance with safety standards is mandatory. Having a thermometer that meets these accuracy standards protects consumers and ensures that pasteurization is effective in achieving the desired pathogen reduction.
