Non-linear junction detector NR-900EK "BLACK KITE"

Non-linear junction detector NR-900EK "BLACK KITE"

NR-900EK "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-900EK "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.
