Handheld Metal Detectors: Portable Security Screening Tools
Handheld metal detectors also known as security wands are widely used devices at the checkpoints from offices to airports or any location. These are light weight devices that detect the presence of metals and create an audible alarm or vibration on detection. The metals such as iron (Fe), nickel (Ni) and cobalt (Co) are detected by active as well as passive metal detectors while as the metals like copper (Cu) brass (Br) and aluminium (Al) are detected only by active handheld metal detectors.
