Heuft USA, Inc. of Downers Grove, Illinois, USA, introduced the Spectrum VX liquid level inspection system, in addition to the ability to inline and inspect high-level liquids in containers. This system also makes it easy to add a continuous inspection device that uses high-frequency X-ray technology to measure the density and physical properties of the product in the container. More importantly, it can also detect chemical contamination and other ingredients that do not match the product's formulation. For example, excessive sugar is mixed in sugarless or low sugar products. This inspection is done on a production line by container, and the contaminated packaging is automatically removed and removed from the production line.
