Contraband Detector Device

The M600P is a hand held device which can positively detect anomalies packed in a scanned item, etc (including the detection of contraband such as drugs, explosives, weapons, currency and much more). This is a fast and effective way to detect contraband concealed in objects such as tires, cargo, doors, walls and any other object or substance that may contain contraband. The principle of operation for the M600P is the measurement of the difference in density between contraband (drugs, explosives, weapons etc.) and the object in which the contraband is hidden.

Contraband Detector Device

The M600P uses low level microwave energy for detection, yet is completely safe. Since it does not use x-rays or nuclear radiation, it is much safer than many other devices in use today. The portability makes it very convenient for rapid searching.

The M600P is a highly effective search tool, handheld and easy to use. The complete kit includes probe, earpiece, battery pack, full instructions and carrying case. Training is available.

Typical Operation The M600P is held in the hand with the opening placed against the material to be measured. The unit is turned on, producing a very Low-Level microwave signal that is absorbed in the test material and also reflected back into the M600P. The M600P compares the signal it produces with the reflected signal. The results are given both audibly and digitally on a meter on the rear panel of the M600P.

Technical Description The M600P Portable Dielectric Tester utilizes patented nearfield microwave technology to measure the dielectric properties of materials. This technology has made possible a very compact and easy to use instrument.

For materials which are the same throughout (homogeneous), a change in reading will indicate something is in there which should not be. This will give a reason to investigate further or to let it pass.

The depth of penetration for the M600P is about 4 ft. in air and is correspondingly less depending on the dielectric properties of the materials being tested. For example, for a bale of wool the depth is about 30" and for a water slurry 6".

Typical Search Scenarios:

In a shipment of asphalt or cement blocks, all will normally look the same. Hidden items will show up as differences from normal readings. Readings are taken from the same points from block to block. Frozen shrimp or fish blocks with items frozen in the center will give different readings from normal. Readings are taken from one or two points in the center of the block. Sealed bottles of wine, whiskey, or any drinkable fluid can be tested without opening. Water based fluids (drinkable), give a markedly different response than explosives or drugs. In a shipment of similar boxes of ceramic fixtures or other commercial items, boxes can be screened to find those which are different from normal. This can be done from outside the unopened box. Tires should be uniformly empty. A tire with drugs in it will show changes from normal. Many other search scenarios have been tried with success. Consult our security professionals.

Advanced Search Scenarios: A user can collect data about the known response of a particular product, and use that from search to search. For example, wine bottles of a known size will always read similarly. A sharply different reading in a new carry on bag would indicate a different substance. In the same way, asphalt blocks will always give the same response. A change should trigger a closer look.
