ITS-ETD1

This device is designed for contact less detection of timers and remote controlled explosive devices.

The device detects mechanical (clockwise based), electromechanical and electronic (including wrist-watch based) timers, and also electronic remote controlled explosive devices occupied by decoders (pagers, cellular telephones based).

The operational principle of the device is based on the reception of electrical, magnetic, acoustic and vibration fields, which are created by electronic and mechanical timers and control circuits of explosive devices, and subsequent analysis of periodic rhythms present in adopted signals.

Analyzing fields:
• Magnetic (H) field (electro mechanical timers, pagers and cellular telephones);
• Electrical (E) field (electronic clock based timers);
• Acoustic and vibration (mechanical timers)

Features:
• Detection of periodic rhythms of mechanical and electronic timers in improvised explosive devices (I.E.D.)
• Detection of electronic timers, including electronic wrist-watch based.
• The device is simple is use, lightweight and compact.
• The device also has the capability to inspect closed packages and handbags with the help of a needle-shaped acoustic    microphone.
• Test target (mechanical, electromechanical and electronic) are available.
