Digital thermometers are greatly misunderstood. Many ghost hunters will receive an EMF spike, pull out the digital thermometer, and shoot. They think the thermometer will pass through the spirit and confirm a haunting.
It doesn’t work like that.
Generally speaking, this makes sense. Ghosts use ambient energy, like heat, to manifest. They suck it up and it causes the surrounding temperature to drop. A digital thermometer uses infrared radiation to detect the temperature in its nearby area. However, its accuracy is poor.
It greatly degrades the farther the laser travels. If you think you see a ghost or shadow person across the room and put the beam on it, the displayed results won’t be accurate. It’s not designed to use ambient temperature. It’s made for hot objects that are right in front of you that you shouldn’t touch.
If you do buy a digital thermometer, get one with an ambient temperature probe. The probe should be fixed to the end of the device and it’s a few inches long. This is the case with a MEL meter, our recommended digital thermometer device and EMF reader. If you get a spike and cold spot (a drop in the ambient temperature by 10(f) or more), then you likely have a spirit. We recommend running an EVP session at this point, too.
