Loma IQ4H Metal Detector System


The metal detector for food and packaging industries, suitable for scanning packed products even with aluminum films

The Loma IQ4H metal detector system with adjustable frequency for metal detection in food and packaging applications is engineered to fit varied operational needs. The complete solution includes the IQ4H detection head, conveyor, and automatic reject mechanism.

This metal detection system is the result of nearly five decades of Loma expertise and innovation in metal contaminant detection for the food sector, and it incorporates optimized mechanical design to enhance performance when locating metallic contaminants using variable frequency (from 31 to 882 KHz).

The 7″ touchscreen interface on the Loma IQ4H metal detector is 33% larger than previous models, offering easier interaction for operators.
