E-Field Detection Meter: find the location and strength of the electrical fields around you

Make sure you check for the presence of electric fields before grounding, since AC current runs up the line of all standard ground cords.  Yes, all the cords sold on the market with every other grounding product from every other store except the PureGround cord carries this AC current!  So if you got a cord from another company and are not using the white PureGround cord, it is running an AC current up the line to your grounding tool and directly to you!  You can test this with an electric field meter.  If you find there is a detectable EMF field emanating from your grounding outlet, simply use a PureGround EMF filtering and shielding cord to protect yourself from this exposure. This extremely simple and effective electric field detector alerts user to the presence and strength of AC electric fields, with these features: Distinguishes 5 levels of electric fields: <10, 10+, 40+, 80+, and 250+ V/m. Provides audible tone whose loudness correlates with the strength of the electric fiel
