EMF Meter, Rechargeable Digital Electromagnetic Field Radiation Detector Hand-held Digital LCD EMF Detector, Great Tester for Home EMF Inspections, Office, Outdoor and Ghost Hunting

  • Why Do I Need An EMF Detector?- There is a good reason I’m always suggesting people purchase an EMF meter once they understand how dangerous long-term exposure to EMF radiation is..
  • No Guess Working Enjoy Your Life- Have a carry-on EMF Reader, then take no guess working with your home devices..
  • Does an EMF Meter Detect WiFi?- RDINSCOS EMF Meter that has the capability of reading radio frequency radiation is capable of detecting WiFi, since WiFi is a type of radio frequency transmission..
  • Auto sound-light alarm- When the test readings exceed the safe value,the EMF radiation meter will alarm automatically, the screen light will flash, and show “Harmful” on display..
  • The EMF METER itself is not electrical radiation- Direct current is not electric radiation, so no worry about the EMF meter itself..
  • Warranty – All RDINSCOS EMF meter are backed by a full 3-year warranty..

Schumann Resonance Generator,Wood 7.83hz Pulse Generator Low Frequency Ambience Generator Mute Schumann Wave Generator with 110V-240V Ac Power Power Supply…

  • Stable Schumann frequency Generator:7.83HZ Schumann Wave Ultra-low Frequency Pulse Generator,It emits the ultra low frequency which provides a stable "ambience" within which you listen to your stereo with more perceived clarity.
  • Schumann Resonances&Earth's frequency:The Earth behaves like a gigantic electric circuit. Its electromagnetic field surrounds and protects all living things with a natural frequency pulsation of 7.83 hertz on average — the so-called “Schumann resonance,” named after physicist Dr. Winfried Otto Schumann.
  • How does the Schumann resonance affect US? Being in the Schumann wave ambience can reduce anxiety, insomnia, and reduce the negative impact of EMF on the body..
  • quiet Schumann frequency Generator：There is no noise at work, you will not even notice its “existence”.
  • With AC power adapter: it can be used in sleep and work when plugged in. In order to achieve better results, it is recommended to stay away from electromagnetic radiation equipment when using.
