In general, security metal detectors are used for the screening of metallic objects in security zones. In almost every common security metal detectors, there are very few Low Frequency or VLF technology used. Low radiation xrays are used in advanced security metal detectors for screening. Usually, security metal detectors are used in prison security, airport security checkpoints, courthouse security as well as government buildings. In addition, they conferences, protect public places and important event.
Security metal detectors are generally divided into two. They are hand held security metal detectors and walk through metal detectors. Super scanner is a hand held security metal detector used by security and law enforcement professionals. Super scanner detects medium sized pistols, knives and razor blades.
The reduction switch in a super scanner is used to minimize sensitivity interference. It also consists of large scan surface and optional holder. Tactical hand held detectors are more advanced and need no adjustment. They detect stainless steel ferrous and non-ferrous weapons. The features include water proof, slip free handle and high impact plastic withstands.
Portable hand metal security detectors are used to detect weapons and other small pieces of metal carried by people. They also check baggage and fabric for both magnetic and non magnetic fields. The features include reliability, sensitivity and long battery life.
Walk through security metal detectors are based on different technologies. Security metal detectors with digital technology provide enhanced target detection coverage.
