Sigma Si-206Z Metal Detector Description

Multi-brand compatibility: The Sigma Si-206Z can be added to existing security checkpoints without having to replace other units. It includes multiple channels and 100 selectable operating frequencies.

Optimum Performance: Scientifically engineered to meet the needs of airports, courthouses, prisons, schools, facilities, special events, mass transit, and other applications that require security inspection.

Detection Performance: This walk-through metal detector accurately identifies ferrous and nonferrous weapons, utilizing superior target detection (3cm steel ball test sample).

DSP Processing: Digital Signal Processor (DSP) based, the device offers greater sensitivity, noise immunity, metal discrimination, detection uniformity, and overall product reliability. The device can pinpoint targets on the left, center, and right sides of the body from head to toe.

Strong Anti-Interference Performance: With advanced analog and digital filtering, the device eliminates potential electrical interference from the environment to ensure detection accuracy. This enables X-ray systems and the metal detector to be placed in close proximity (30cm) to each other.
