A metal detector is an electronic instrument that creates an electromagnetic field and listens for disturbances caused by metallic objects. When metal passes through or near the field, the device registers a change and alerts the operator through sound, light, or vibration. From food and pharmaceutical production to public security screening, metal detectors protect quality and safety by catching contaminants and threats before they cause harm. This guide covers the Top 10 Metal Detector Manufacturers in India and explains where each excels, so you can match solutions to use cases. You will learn about conveyor, gravity, tablet, handheld, and walk through systems practically.
