CEIA MS21 metal detectors from Heat and Control simultaneously use a broad spectrum of inspection frequencies to detect all metal contaminants. Its patent-pending multi-spectrum technology accurately identifies the difference between a metal particle and specific product effects such as water content or temperature variations that can lead to costly delays, product re-inspection and waste. CEIA multi-spectrum detectors automatically learn and track product effect conditions. Its Auto-Learn system selects, displays and stores the optimal sensitivity settings for up to 500 products. A single-button preview of detection settings, including the range of frequencies used, sensitivity level, metal type and particle size, also helps reduce detection errors.
