Non-linear junction detector NR 900 EK «BLACK KITE»
NR-900 EK «Black Kite» Field Non-Linear Junction Detector (NLJD) is intended for detection various electronic devices on the ground as well as covered by soil, snow, or concealed in building structures.
NR-900 EK «Black Kite» NLJD ensures effective detection of the following items:
- Transmitting and receiving components of radio-communication, alarm, and remote control systems;
- Electronic and electro-mechanical timers;
- Acoustic, magnetic, and optoelectronic sensors and miniature TV-cameras.
NR-900 EK «Black Kite» NLJD features high sensitivity double channel receiver (2-nd and 3-rd harmonics) that ensure low false alarm rate when detecting metal foreign matters.
Aerials with circular polarization eliminate a risk of «lost» objects when orientation of the aerial system changes.
