EMF Meter for Ghost Hunting
This can be used to backup other paranormal evidence such as cold spots and EVP recordings. Just remember to check for genuine causes of EMF spikes. For instance, electrical equipment, overhead power lines, mobile phone and walkie talkie signals.
Asking the ghosts to move away from it, and move closer can help validate any measurement you get. As this will prove it is paranormal. And that the entity is intelligent and not just residual energy.
What is the EMF Meter?
They were not originally designed for paranormal hunters. They were created for diagnosing electrical problems. Such as diagnosing issues with electrical wiring and power lines. And for measuring magnetic field and electromagnetic field on electrical appliances.
Also known as the Electromagnetic Field detector. It has many day to day uses. It measures the quantity of electromagnetic fields given off by anything electrical.
It has found its way into the paranormal field as spirits are made up of electrical energy. And the meter can be used to detect them as well. There are many spirit hunting phone applications that claim to work as EMF detectors.
None of these will give accurate measuring as mobile phones do not have an electrometric field meter built in. For accurate results you will need a genuine magnetic field EMF detector like the K2 meter. They catch phone signals because they have a wide range.
What does it Measure?
They pick up on magnetic fields created by electrically charged objects. The charged objects need to have an alternating current. Or the device needs to move past the fixed field. There are two variations of the meter, a single field and a tri field meter.
The single field measures the magnetism in a single direction. But the tri-field measures in three directions. The cost for a tri-field meter is usually higher as they pick up readings that the single axis meters miss.
How the EMF Detector fits into paranormal investigating
It’s a well established theory that spirits and ghosts are made up of a electromagnetic field. And emit their own electrometric fields. This makes it a perfect ghost detector.
A good way to start your investigation is to walk around with the device. Then when you receive spikes in readings that are not from a electromagnetic field there is a possibility it’s something supernatural.
To prove the authenticity, you can walk away from the spot and back again to see what happens to the reading. Or you can ask the spirit to move closer and then step back. To see if the spikes indicate the spirit has done this.
Multi Measurement Sensors
Some of the advanced instruments measure multiple factors including magnetic field, electromagnetic fields, radiation, temperature, micro Tesla, microwave, radiation exposure and more.
Measuring the Field Radiation Range
Measuring the field radiation range is a growing concern. Especially since the 5 Ghz WIFI. Its a frequency range believed to be harmful to humans. Because of this the price of radiation measurement sensors has increased dramatically.
Some people believe 5 GHz exposure causes field radiation. But some people don't believe it. There are many other device that cause radiation too so its handy having a handheld device to measure it.
Triple axis meters x y z
Not all meters are created equal. The majority of electromagnetic field detectors are single axis. These are usually the cheaper sensors and only measure field strength in one direction. The manufacturer will usually put this sensor in to keep the price down. Some of these meters are near free in price.
The triple axes x y z meters are much higher in price. And measure field strength in all 3 directions. These better quality meters offer much more precise measurement. Also they detect higher ranges of electromagnetic field emf.
Just about all electric instruments generate a magnetic field or electric field, on various frequency range. Measuring electric field and magnetic field is quite simple and straight forward. With a digital handheld measurements meter.
Electromagnetic Field and the Supernatural
Electromagnetic field changes usually happen when something supernatural occurs. This is why investigators take digital measuring detector instruments and devices on ghost hunts. They look for measurements that can't be explained. They then look at any value that is out of the norm. Using the displays and data from the measurements that are out of the ordinary. This can backup strange happenings.
You should debunk and test anything you pick up. You can do this by checking its not too close to anything electric such as a phone, light switch or television. If you can't debunk it, it strengthens the evidence you get and will push it more towards being something unseen.
Is it worth having multiple EMF Meters?
If your investigating on your own outdoors you should be fine with one meter. If you have a team working with you, and you want to split up, it would make sense to have spare ones so multiple groups could use one at the same time.
If your in a large indoor location its handy putting a different ones in each room. If you have one with a sound alarm it can notify you from a distance which is very handy. And will help you catch more paranormal evidence should things occurs in multiple places.
EMF meters are a staple piece of equipment for paranormal researchers. Just about all of them keep one to hand on a hunt. The most popular by far is the K2, its well priced, reliable and easy to keep in your pocket.
The lights are quite bright, and it has a good sensor that will pick up a large frequency range. There is no LCD display but the different lights will alert you the level of frequencies it picks up. The sensor probe measures in guass. And the levels are shown with the lights on the front. It's high accuracy and the different frequencies displays via the lights.

There are many Meters manufacturers such as Trifield and DAS. Ideally a triple axis with an LCD display, data logging, high accuracy, external probe, wide frequency range all at a reasonable price. The Trifield and the Mel Meter range are excellent and cover all these bases.
Active and Passive type Sensors
Active sensors are sensing devices which contain components that are active. This usually gives a more precise measurement with respect to passive counterpart. A passive receiving antenna collects energy from the electromagnetic field being measured. This makes it available as an RF cable connector. The signal then goes to the spectrum analyser. And field characteristics can be someway modified by the presence of the cable. Especially if it’s in near field conditions.
Alternatively, a good solution is to transfer through an optical carrier. The electric or magnetic field component is picked up with the active probe. The basic components in a system are a receiving electro optical antenna. Which is able to transfer to an optical carrier. The individual electric or magnetic field component is picked up.
Then it’s returned in the form of an electrical signal to the output port of the converter. The modulated optical carrier is then transferred by means of a fibre optic link. This leads to a converter which extracts the modulating signal. Which then converts it back to an electrical signal. The electrical signal can then be obtained and sent to a spectrum analyser. With a standard 50 Ω common RF cable.
Sensitivity and Calibration
The most electromagnetic fields encountered generated by household or industrial appliances. Most of the EMF meters available are calibrated to measure 50 Hz and 60 Hz. These alternating fields are the mains frequencies used in the US and European countries. There are some other meters which can measure fields alternating at as low as 20 Hz. These are usually much more expensive and are generally only for specific research purposes.
All calibration should be carried out by an ISO 17025 accredited laboratory. And every calibration certificate issued. Which should ensure that the instrument used to carry out EMF measurements are accurate. Any meter giving incorrect readings can result in death or injury. Especially when used for work purposes by electricians and electrical engineers.
Research on its Harmfulness
There’s a big disagreement over the safety of EMF. Which is because there’s not much research suggesting that its actually harm human health. According to the World Health Organization’s International Agency for Research on Cancer. EMF is possibly carcinogenic to humans. They believe that some studies show a possible link between EMF and cancer in people.
There is one item most people carry every day that which sends out EMFs which is the mobile phone. Use of phones has increased significantly since they were brought out in the 1980’s. Concerned about human health and phone use. Their researchers began what would become the biggest study to compare cancer cases in phones users back in 2000.
The types of EMF exposure
There are two main types of EMF exposure. Low level radiation which is called non-ionizing radiation. This is mild and is thought to be harmless to people. Appliances like microwaves, mobile phones, WIFI routers, power lines and MRIs. These all send out low levels of radiation.
High level radiation which is called ionizing radiation. Is the second type of radiation. It’s transmitted out in the form of ultraviolet rays like from the sun. Things such as X-rays from medical imaging machines create this type. EMF exposure intensity decreases when you increase the distance from the object that’s creating the waves.
