Food safety testing equipment

With the increasing attention of the country to food safety, the scope of food testing continues to expand, and higher requirements have been put forward for the accuracy of testing instruments. Food testing covers a wide range of items, such as pesticide residues, veterinary drugs/antibiotics, food additives, heavy metals and harmful substances, toxin microorganisms, conventional physicochemical properties, and contact materials. Specially designed instruments are required for these different testing items. This article will summarize 176 commonly used instruments in food testing laboratories, providing strong support for your food safety testing work.
