-100 DBW 920 Mhz Non-linear Junction Handheld Metal Detector for
Wall 75 cm Below
The NLJD uses the latest technology of non-linear junction field to
detect hidden electronic detonating devices, and has nothing to do
with opening and closing of the devices.
Through analysis for received second and third harmonic component,
this NLJD can distinguish electronic devices containing
semiconductor devices, and it can also identify false junction
linking metals and their oxides.
The NLJD has reached world’s advanced level in detection range and
ability to penetrate, and possesses the latest design of manual
adjustment system for power in launch. On the one hand, to ensure
the detection rate, on the one hand, to prevent wrong switch and
misoperation for electronic devices caused by improper transmission
power as well as damage to electronic components due to too large
1. Deep range of detection, detecting whether electronic detonating
device exists in load-bearing wall 75 cm below, e.g., under the
sofa seat, under the concrete.
2. Wide range of detection, is able to detect all the
radio-electronic devices from low frequency to high frequency and
low frequency electronic devices that other equipment can’t detect.
3. Possessing manual adjustment function for power, preventing
wrong switch and misoperation for electronic devices caused by
imporper transmission power.
4. Video and audio for alarm.
5. Achieving a better detecting effect through converting
modulation mode of detection signal of transmitter.
