Protecting consumers and maintaining brand integrity hinges on the ability of food and pharmaceutical manufacturers to deliver products free of foreign metal contaminants. Drop-through systems are essential for checking agricultural raw materials, granular foods, powders, and items processed with metal equipment.

The Sentinel 4000 Drop Through System (Sentinel 4000D) is engineered for high-sensitivity detection of ferrous, non-ferrous, and stainless steel metals. This system incorporates Multiscan technology with up to five user-selectable frequencies to optimize performance, increase the probability of detection, and find smaller contaminants. The Sentinel 4000D is designed for maximum uptime and includes features like an easy-to-use 7" color touchscreen, Modbus serial or Ethernet connectivity for remote diagnostics, and an HD model for harsh environments.

Discover how this robust system provides faster and more precise analysis to comply with safety standards, helping manufacturers save money from costly recalls.
