Edmund (Pseudo)Scientific Sells “Ghost Detectors” & Other Woo

Posted by mattusmaximus on September 14, 2009

A couple of weeks ago I became aware of something that, as both a skeptic & science teacher, shocked me: Edmund Scientific, one of the oldest & most respected outlets for selling science equipment for educational use, has gone over to the dark side.  They are actively marketing & selling paranormal woo…


What are these products that Edmund (Pseudo)Scientific is now selling on their website?  They are…

EMF Ghost Meter – This is nothing more than a standard EMF (electromagnetic field) detector, which usually detects EMFs that are low frequency, such as radio & microwaves.  I have no beef with Edmund selling EMF detectors (I even have one in my classroom), but what galls me is the manner in which they are marketing this device.  They are actually calling it a ghost detector – and by doing so they are giving credence to the pseudoscientific flummery of the paranormal woo-meisters!  As they say on their website:

Detect Paranormal Presences

The preferred unit of paranormal investigators, this Ghost Meter can be used by laymen with professional results. The unit responds instantaneously to EMF fluctuations and spikes in energy with a detecting range of 50 to 1,000 Hz. The VLF range is 1,000 to 20,000 Hz. An easy-to-read LED display and silent on/off push switch make for seamless, simple operation.

Such devices are often used by so-called ghost hunters as they bumble around in the dark, freaking themselves out at every cool draft of wind & creaky sound they hear.  In reality, there is absolutely no reason to think that EMF meters are detecting any kind of “ghostly entities”, as a simple application of Occam’s Razor often shows that what the meters are actually detecting is the low-frequency EM-waves given off by nearby lighting fixtures, electrical lines, or even the other equipment carried by the ghost hunters themselves!

But if you thought that was bad, it gets worse.  Here are some other gems that Edmund (Pseudo)Scientific is now selling…
