Many people have asked about Electromagnetic Field (EMF) detectors and how do they work and which ones are the best ones to use for paranormal investigating.
Like most things you really need to use as many meters as you can and make a determination as to which one you personally prefer. I have a nice variety of meters to choose from. Since there is only one that was designed for paranormal investigation that is the one we will talk about, and that is the Mel-8704.
Currently there are 10 different models of the Mel-8704, 5 have a green display and 5 have the red display. There are also differences as to what each can do, we will discuss some of the most popular features here.
Q – The Mel meter is listed as a 2 axis meter, what does this mean and what does it measure?
A – The Mel-8704-2X Utilizes to independent coils for formation of the dual axis circuit. One circuit is calibrated to cover 30Hz -300Hz (ELF) range and the other goes down to 20Hz. The purpose of this is to try and identify if a “Spirit” can manipulate and communicate easier using the lower 20 Hz (ULF) range. It’s just a concept to try and prove if “Spirit” vibration can be more easily discerned at other ranges. The cool part is that both can be used simultaneously and a cross comparison can be made by the observer / Investigator.
Q – What is the effective range of the Mel meter?
A – As with all EMF meters, the Mel meter detection distance depends on the location and strength of the radiation source.
Q – The meters description mentions a “Burst” mode, what is that?
A – The Burst/FAST mode has always been a part of the Mel features. Basically, you just “escape” out of the temperature measurement mode and then allocate 100% of the microprocessors scan time to update the EMF readings. The suggestion for investigators is to use the meter in this mode. Then, if you feel a temp change, switch over to the dual readout mode….it’s easy to do and only takes 3 seconds to do. The display update in the Burst/FAST mode which is around 10X/second is excellent for sweeping a room to uncover EMF sources or for detecting a fast EMF spike or dynamic change while using the Mel record mode.
Q – What is the effective range on the thermal mode?
A – The Mel uses a precision “K” type of thermo-couple probe. The bead reads Ambient (air temp) temperature only. As such, it can only sense a temperature change that comes in contact with the beaded tip part of the probe.
Q – The newest meter has a vibration and touch detection capabilities. It is says in the documentation that this is accomplished via an accelerometer. Does this device use a single axis of, 2 or 3 axes? Also, does this device utilize a piezoelectric electric effect (microscopic crystal structure) or capacitance?
A – The Mel-8704R-Vibe utilizes a Crystal based piezo accelerometer. It can be calibrated to detect very, very small vibrations.
One of the newer models is a combination Mel meter and KII with an audible alarm.
Here are a couple of movies which explain how the unit works followed by the meter being used in an investigation.
