EDI Meter

EDI Meter

An EDI Meter combines several meters into one device. It has a thermometer, an EMF meter and a Geophone. There is nothing remarkable about this device, but it does cut down on the amount of kit (and batteries!) that need to be brought on an investigation. It saves have three separate devices to measure the three elements. An EDI is quite a large device, certainly not designed to be in the pocket but this is not the purpose of the device. It should be placed on a table or in a part of the room or space being investigated so that it can be seen periodically. It can be useful to know if the temperature has increased or decreased as well as a spike in EMF energy at the moment that someone in the room heard/saw/felt something or if other meters detect a change.

Like all EMF meters, they are prone to other devices like mobile phones, hearing aid loops and electricity and will pick up these signals with ease. The built in Geophone is very useful as this converts noise into a visual display, so if this lights up when placed in a quiet area or in a locked off room then this would be an excellent device to see the noise if it was inaudible at the time.

We like the EDI because of the compact nature of the device, the build quality is excellent as well as the rugged look and it combines several meters in one device. The new model has a pressure sensor, a humidity sensor and a data logger which for paranormal investigations make this useful to download the data.

This is a purpose-built device for the paranormal and is only available from the US, Ghost Stop is an authorised seller and the cost is $200

Infrared Thermometer

Infrared Thermometer gun

Our thermometer guns measures temperatures from -50°C – 420°C. It is designed for; hot water pipes, cooking surfaces, axle bearings, heating, air condition, food etc.
The built-in laser is for precise aiming. We use it for detecting spikes in temperature in the room, mostly around people if they report a change of temperature.
One of the biggest misconceptions with these thermometers is the use of the laser. The laser is there so you know what you are pointing it at. It does not measure the temperature at the laser point. The laser cannot measure temperature.
Yet time and again people think that they are measuring the temperature wherever the laser points.
All of these types of thermometer have a radius that they measure the temperature at, so if you imagine a cone coming from the temperature gun widening to about 1 meter wide at 1 meter away from the gun, this is the area in which the temperature is measured. The further away the source the bigger the cone.
To get a more precise temperature reading, you need to be as close as possible to the temperature source or fluctuation.
We like these temperature guns because of the ease of use, easy to carry and it is a quick way to establish whether there is a temperature fluctuation or whether it is just someone imagining that they felt a temperature change. Usually we also have our Thermal Cameras on hand to get a better thermal photo and to see if someone is experiencing a temperature fluctuation.
These have become more popular recently (June 2020) due to the Coronavirus outbreak but you can still pick up a decent one from eBay or Amazon for about £15 (look in the tools section, not ghost hunting)
