Handheld Non Linear Junction Detector (NLJD) Detects all types of electronics - whether active, passive or even switched off. PRODUCT FEATURES • Detects all types of electronics - whether active, passive or even switched off • Easy to operate with an intuitive user friendly interface • 2.4 GHz Transmit - up to 4 Watts • 2nd Harmonic (4.8 GHz) and 3rd Harmonic (7.2 GHz) Receivers • As powerful and sensitive as much larger so called ‘portable’ units • Detected material Indicator ‘Silicon’ or ‘Metal' • Will even detect the latest NANO SIM cards from up to 20cm • Audible Tone and Demodulation Function through speaker or earphones • Battery life up to 4.5 hours • Weight just 700g • Machined Aluminium Enclosure with Moulded Plastic Antenna Cover • Supplied in a compact Military Standard carry Case Principle of operation: Semiconductor Electronics are used in all modern electronics and are made using Silicon. When high frequency radio signals are transmitted directly over silicon they produces a strong second harmonic frequency of that radio signal. Other materials such as some bi-metals or oxidised metals can respond with a third harmonic signal. The EDD-24T transmits a focused directional signal on 2.4 GHz (ISM Band Type B). It receives on 4.8GHz (Second Harmonic) and 7.2GHz (Third Harmonic). The highly sensitivity receiver will respond to any signals produced on the 2nd Harmonic by even the smallest piece of Silicon such as that used in SIM Cards, Mobile Phones, Bugging Devices, Voice Recorders, Covert Video cameras etc. Importantly those devices do not have to be in use, in standby or even have any power connected to them to be detected. The 3rd Harmonic receiver acts as a valuable confirmation for signals that may be ambiguous or are not a threat such as those in oxidised metals, bi-metals etc.
