EMF Meter, Portable Digital Radiation Detector, Rechargeable Ghost Hunting Equipment, Handheld EMF Detector for Home/Outdoor, Electric/Magnetic Field/Ghost Detector - LED Light & Sound Alarm Black

It's pretty handy detecting EMF fields around your house. You may want to turn off the alarm for this thing because it goes off on any reading. It was beeping from being to close to LEDs. I didn't really find anything unusual around my house just what you would expect like the microwave or surge protector. Not sure about the ghost detecting feature on this.

EMF Meter, Portable Digital Radiation Detector, Rechargeable Ghost Hunting Equipment, Handheld EMF Detector for Home/Outdoor, Electric/Magnetic Field/Ghost Detector - LED Light & Sound Alarm GrayThe EM radiation tester comes economically packaged in a plain brown cardboard box with a line drawing of the tester printed on the top and manufacturer's specs on the bottom. Inside the box, is the tester itself in a blister pack baggie, a USBA to USB mini charge cord, and a small fold-out instruction booklet.Plugging it into charge, the entire LED screen lights up, and the upper right-hand corner has a battery that pulses an ascending pattern showing that the battery is charging. I'm a little disappointed that this uses a USB mini to charge, most devices these days are using a USBC. At least it's not a proprietary charging cable.Interestingly enough, while you're putting this on to charge, it also turns the device on. It shows the temperature of the room in the center of the screen, in either Celsius or Fahrenheit, choosable by a button on the front of the unit.The instructions for the unit really aren't a lot of help. They go into a lot of very generalistic warnings about the dangers of electromagnetic fields which of themselves are true, yes and an overdose of electromagnetic fields can help you. Do you have an overdose of electromagnetic fields in your everyday life? Generally, no. Practical uses for this device though would include testing your microwave to see if you have a leaky door or similar things such as this. Or, you can pretend your Ghostbusters like the guys on TV and try to find a ghostie in your house where I live, it'd be harder to not find a ghost in the house.All in all, this is more a toy for entertainment, rather than a technical tool.

It is a good Detector for EMF and electric fields. It also has a temperature monitor, which is a useful feature for those who like to hunt for ghosts. I wouldn't know how accurate this device is but it does do what it is supposed to do. I just tested it around my wall sockets and it did detect electrical radiation.
