Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a food heavy metal detector. Background Art

[0002] During food processing, essential additives are often added to ensure product quality and safety. However, these additives may inevitably contain heavy metals such as lead, arsenic, chromium, cadmium, mercury, cobalt, and manganese.
