These two meters above are a sample of the standard hand held units available in most shops or are available on the internet.

It has been said by many ghost investigators that paranormal activity (ghosts etc) produce or use electrostatic fields to appear, so by the use of electronic electrostatic meters we should be able to detect their presence. Some people are sensitive to these fields of static and can feel them as they walk though the room. We have used these meters to sense these forces and track them to it's source, many things can produce static electricity and we are all sensitive to it effects.

 

In some environments, air ions are either deliberately introduced -- by using an ionizer -- or they may be accidentally present, such as from nearby sparking of high-voltage sources. These ions can either help remove surface static electricity or add more, depending on the situation . If "accidental" ions are present, the meter can be used to measure how many excess ions per second are hitting a given area ("excess" meaning either more negative than positive or more positive than negative, so thats when excess ions are present, they will charge surfaces either negative or positive).
