ION Detectors

What are they?

To put it simply they are used to measure ions. Indoors you will usually find a higher concentration of positive ions (ions being electrically charged particles) to outdoors. Positive ions are oxygen with an electron removed whereas negative ions are oxygen with an added electron. So for example pollution and air conditioning may create positive ions as does a thunderstorm.

Why use them for paranormal research?

Ion detection is often used in conjunction with EMF analysis for a dual method of detection and many of the same points mentioned in reference to EMF meters are also relevant to Ion detectors!
Paranormal experiences do seem to occur more often when there are lots of negative ions around so there may be a link!
It is claimed that either a ghost or presence may give off both negative and positive ions when they manifest and so air ions may be another bi-product of paranormal activity! Alternatively it may be that certain conditions may be conducive to paranormal activity.
For example a room charged with ions may be a precondition for paranormal activity to occur.
Ions may disperse quickly but not hopefully before an ion detector would pick them up.
