SDM4-CTGA. Next-generation Walk-through Metal Detector with very high discrimination and excellent immunity to the external electromagnetic noise. Friendly-user, it does not require special training for its installation. The compact and light design together with the extreme simplicity of assembly makes it ideal for mobile access control gates such as cruise ships, schools and clubs. Developed to permit the highest traffic flow rates without jeopardising control, the SDM4-CTGA Walk-through Metal Detector is ideal for security professionals all over the world.
