What about the ADE 100, ADE 101, ADE650, ADE 651, ADE 750, ADE 751?

The makers and sellers of the ADE or "Advanced Detection Equipment" claim:

  • "ADE650, ADE 650, ADE651, ADE 651, Advanced Explosive and Narcotic Detection Equipment Non-Vapor Overt or Covert operation Detection range exceeding 1000 metres!* (in ideal conditions) Can detect all current known drug & explosive based substances. .."
  • ADE–650:PORTABLE EXPLOSIVE DETECTOR. This equipment detects traces of both particulates and vapors, allowing for non-invasive searches of luggage, personnel, mail and containers without the use of radioactive source or external carrier gas. The working principal is based on electrochemical (Thermo-Redox) detection. The range of detection is around 50 meters with obstacles and up to 650 meters in outdoor parking lots, the unit can also detect explosives submerged in water or buried underground. Detection from a hovering helicopter is also possible [emphasis added]
How does the ADE-650 use Thermo-Redox technology? According to the National Institute of Justice report this is Thermo-Redux technology:

  • Thermo-redox technology is based on the thermal decomposition of explosive molecules and the subsequent reduction of NO2 groups. Air containing the explosive sample is drawn into a system inlet at a rate of approximately 1.5 L/min. The air is next passed through a concentrator tube, which selectively adsorbs explosive vapor using a proprietary coating on the tube’s coils. The sample is then pyrolyzed to liberate NO2 molecules, and these molecules are detected using proprietary technology. Those interested in additional information on this technology should contact Intelligent Detection Systems (see table 4), which now markets the thermo-redox based equipment formerly marketed by Scintrex.
  • The thermo-redox system currently marketed, the EVD-3000, is a hand-held unit that costs approximately $23K, pictured in figure 11. It can analyze both vapor and particle samples, and contains no radioactive source. Since only the presence of NO2 groups is detected, this technology cannot distinguish among different explosives and potential interferences that contain NO2 groups. Thus, the system identifies the presence of an “explosive-like” material, without identifying a specific explosive. Furthermore, the technology cannot detect explosives that do not contain NO2 groups.
A REAL Thermo-Redox detector

The "Thermo" in Thermo-Redox comes from the fact the sample is "pyrolyzed" meaning it is heated to the point of having a chemical reaction where the molecule is broken down into smaller parts. "Redox" is an abbreviation for a reduction/oxidation chemical reaction.

How does the ADE burn and chemically react with a substance hundreds of meters away?! Especially with no power source!?

How does a company get away with blatantly lying about a product designed to detect explosives???

It is amazing that the breadth of the breadth of this story remains largely hidden, especially at a time when governmental fiduciary responsibility is so much at the fore.

Thanks for making the information in your blog available. A post back to your site has been published on Anomaly Agnostic ( http://anomalyagnostic.blogspot.com ). The links to the government test on Sniffex were especially interesting, as well your listing of the surprisingly large number of other spurious devices out there.

As the old saying goes, "Fool me once, shame on thee: fool me twice, shame on me."

Or, to paraphrase a commentator on a related post put it, what ever happened to the good old days when you could buy a dowsing rod for only $100?

Thanks, and keep up the good work!
