How non-linear junction detector work?

How does a non-linear junction detector work? The NLJD antenna head is a transceiver (transmitter and receiver) that radiates a digital spread spectrum signal to determine the presence of electronic components. The receiver measures the strength of the harmonic signal and distinguishes between 2nd or 3rd harmonics.

What is use of non-linear junction detector?

The non-linear junction detector, or an NLJD, is a device that illuminates a small region of space with high-frequency RF energy. In its basic form, an NLJD can also detect things that are not themselves electronic in nature, so the use of the device requires a modicum of skill and experience.

What is explosive Vapour detector?

Explosive detection techniques can be broadly classified into two main categories: bulk detection and trace detection. Vapour detectors examine the vapour emanating from a liquid or a solid explosive, and because some explosives have a low vapour pressure, these detection techniques would be very sensitive.

How do explosive vapor detectors work?

Colorimetric detection of explosives involves applying a chemical reagent to an unknown material or sample and observing a color reaction. Common color reactions are known and indicate to the user if there is an explosive material present and in many cases the group of explosive from which the material is derived.

What can a non linear junction detector detect?

The EDD-24T handheld Non Linear Junction Detector (NLJD) detects the presence of semiconductor circuits that are used in all modern electronic devices such as mobile phones, tracking devices, listening devices, covert cameras, digital voice recorders, SIM cards etc.

What does the Orion 2.4 HX non linear junction detector do?

The ORION 2.4 HX Non-Linear Junction Detector (NLJD) detects electronic semi-conductor components in walls, floors, ceilings, fixtures, furniture, containers, or other surfaces.

Who is the distributor of the JJN edd-24t non linear junction detector?
