EH-NLJD-simple

A nonlinear junction detector with up-to-date threat detection capability to detect small objects such as

SIM cards. Made as simple and as low cost as possible to be affordable.

EH-NLJD-simple is designed to detect any electronic equipment hidden in walls, furniture, containers and person’s body in or under clothes and also in hand luggage (bags, packages, etc.).

EH-NLJD-simple is a hand-held device in which the main unit integrates a transceiver, antenna, power supply, control and indicating panel.

  • 2.4 GHz ISM frequency band and the low transmitted power EIRP less than 100mW conform with the Short Range Devices standard (EN 300 440). 
  • Circularly polarized transmit and receive antenna removes the risk of missing a threat due to incorrect antenna polarization.
  • The combination of high sensitivity and low transmitted power provides adequate detectability. A simple and user-friendly interface allows you to work quickly and easily analyze the results.
  • The telescopic stick is connected with a standard 1.4 inch mount and can be changed.
  • The use of standard batteries allows the possibility of easily replacing them if necessary.

EH-NLJD-regular

A nonlinear junction detector is made  in the same case as the EH-NLJD-simple model,

but with a third harmonic receiver.

EH-NLJD-regular  has the following additions to the EH-NLJD-simple model

  • Receiver of the 2nd and 3rd harmonics of the transmitted signal. Two-color LED scale. Red – 2nd harmonic, Green – 3rd harmonic.
  • 2.4 GHz ISM frequency band and the low transmitted power EIRP less than 500mW conform with the Short Range Devices standard (EN 300 440). 
  • The transmitter power is adjusted automatically so that the harmonic responses are within the range of the scales.
  • Built-in charger and external charger.

Three-channel detectors EH-MD3 and EH-MD3-mini

Get more information about the properties of an object.

EH-MD3 and EH-MD3-mini are hand-held devices in which a detector of switched-on electronic devices is combined with a metal detector and a detector of ferromagnetic objects.

The pulse metal detector channel is designed to detect every type of metal.

The detector of ferromagnetic objects channel is based on the measurement of the magnetic field vector. The magnetic field is generated by the earth and distorted by objects made of ferromagnetic materials such as large iron objects, magnets, etc. Magnets are included in the speakers and microphones of phones, which allows phones to be detected even when they are off.

The Switched-On electronic devices detector channel can be used to find the different types of switched-on electronic devices, namely digital timers and remote-control units, photo and audio/video recording devices, laptops, GPS trackers, cell phones of all standards (also in a sleeping mode) and etc. The principle of operation is based on the registration of the magnetic field pulses generated by the current pulses of switched-on electronic devices.

All detection channels have one working zone, separate scales and work simultaneously. An operator receives more information about the properties of the searched objects.

Outwardly EH-MD3 is similar to a manual metal detector, which makes it possible to search without causing suspicion of the person being inspected. The device is easily operated and inexpensive.
