I stood on my deck and pointed the tester towards the power lines by my house. i did not get any readings emf showed 0. is this conclusive ?

  • If the power lines are far enough away and not transmitting a high current load you shouldn't get a reading. The big huge transmission towers can show high levels of EMF. The lines to your home shouldn't show much. Old fluorescent lights and old CRT monitors can leak a lot of it.

Can you use this to test EMF from power lines near house ?

Is there a way to turn off the alarm / sound?

  • yes, I think momentarily pressing the power button will do this (the alarm toggles on and off using the power button)

Will this tell me if the smart meter on my house is putting harmful radiation into my kids bedroom? Is it easy to read and use?

  • I haven't used it, I bought it for a gift. I'm sure it will.

    Conforme à la description ce produit me laisse sur ma faim dans la limite ou parfois il se bloque dans la mesure des ondes vous devez en fait retirer l'appareil et reprendre la mesure. Toutefois ce pour quoi j'en ai l'utilité ce n'est pas très gênant en effet le but est de détecter les fuites d'ondes ou l'exposition excessive à une distance donnée par exemple. Vous pourrez donc sans problème remédier à vos problèmes de rayonnement. Je recommande
