Which electromagnetic field meter to choose for your home?

Question

Iron

Hello,
I decided to purchase a device measuring electromagnetic fields. For personal purposes, in order to place the equipment at a safe distance from residential premises (or places of frequent stay), to yourself and friends.
I would be grateful for advice, does anyone understand such devices, in lineups, how to choose, where can I buy cheaper?

UPD
For Artem and other boors.
Your behavior is an indicator of your level of intelligence. Please be silent and do not grumble if you do not have experience with these devices.
Would you dare to answer like that to a person’s face, or are all such heroes only through the Internet?
If you personally do not want to use such devices, this is your personal opinion, it is not a reference and does not necessarily have to coincide with the opinion of everyone.
Before asking a question, of course, I googled and briefly studied these devices. I am not a theoretical physicist, but my knowledge at school was solid.
I just didn’t find the prices, according to the characteristics, too, without understanding it to the end, I don’t want to buy.
Yes, that's what they are called, UPD 2 Electromagnetic Field Meter Thanks to Bonya09 and John Smith (and others who I didn't notice) for your answer "You don't need a device if you and your friends don't have bare magnetrons or homemade air defense radars in the apartment. "


Let's hope that among the neighbors there are no desperate experimenters who have seen enough homemade products with magnetrons on YouTube.
Yes, and in the yard there are transformer booths, sometimes you leave the car and walk by yourself. Sometimes at all, people live near high-voltage power lines.

I didn't think my curiosity would hurt anyone's feelings.

Answer 1

And that's what it's called? electromagnetic field meter? very interesting..

Answer 2

But I’m wondering if anyone applied to such a laboratory https://eko-analiz.ru/elektromagnitnye-izlucheniya... to order a service for checking electromagnetic radiation? It is very important to know if they are doing their job well.
