"RF" detector for lcd/led displays/tvs?

sake
I dont tolerate led or lcd tvs or monitors. Only a tiny bit, of course depending on size, lightstrength and distance. Even Smartphones and tablets. What detector do I need to measure the bad radiation that these Things emits?

Thanks.

You could try a dirty electricity meter.  Some TVs make more dirty electricity than others.
But this only tells you how much EMF is going in the wiring, not coming out of the TV.

Generally not a lot that you can measure.  E fields can be high unless a coax cable is hooked up which will ground the TV.  Most TVs have 2 prong, no ground.  So the coax can ground it, if it's a grounded coax cable which they all should be if installed properly.

M fields are pretty low also, and RF fields will be in the range that can't be easily measured.  An AM/Shortwave radio works best, and will buzz loudly when closer to the TV.

There is also the ESmog Spion meter that can measure light emissions.  I don't think it's the light coming out that causes problems, unless it's flickering then maybe it can cause headaches, but not skin burning.  For me face burning is EMF related, not light.
There are USB laptop screens that are supposed to be better, but I haven't tried any.  It plugs in the USB only, not in the power outlet.  If you use that with a laptop on batteries it should be better, but you also have to ground the laptop.  There are USB ground cables that you can use to ground any laptop.

I find laptops that cause minimal heat and don't have a fan running most of the time are best.  More heat and fan running will emit more EMF.

With the E-Smog Spion, and its switch to NF, and the telecopic antenna out, you can measure the *dirty air* coming from all sorts of devices.

Start with an AM radio like used in my videos. This has some range and can detect my monitor. That is very cheap. The E-smog spion has full range but is expensive.

E-smog spion.. Is it Worth 550 euros?

(How different is it from scanning with am radio?)

It only costs EUR 295,- (incl German VAT)

Of all my measuring equipment, I prefer this one.

It seems better to follow the advice from somebody who has one, and has experienmce with it.
The E-Smog Spion does not only measures high frequencies, but also low frequency fields.

i have an Esmog Spion with Light Module " Solar" since last week.

I don't have all meters i want yet, but i already dare say that the Spion
will probably become my favorite meter.
The sound function is very useful !
This meter outputs different sound signatures for different sources
for LF as well as HF. I traced 2 problems to it's source, which i couldn't
with AM radio's.
An AM radio is still very useful, especially for beginners,
i have radio's that detect things further than any other meter.
The Spion doesn't have digital readings so i still need the Cornet ED88T as well.
It seems you need a couple of meters to get a complete picture.

Just buy a very low wattage screen/ tablet with no hard drive or fan. 12vDC motors are the dirtiest things about for magnetic and FRI pollutions. Sellers should have to put the wattage of devices on the spec. My monitor is less than 10 watts but they don't make them that energy efficient any more cos they think bigger and hotter is better and we cannot choose cos they don't tell us this info..Cheap AM radios are best for showing emissions.  Never be within the range you can pick up as a fuzzed mess. Use wired every thing with ferrite chokes. I only use 12vDC from a linear power supply. Avoid 5v USB as this  is harder to get clean because of pulsed chipped transformers power supplies. Who decided on 5 volts? Why not 6? Sadly most USB devices cannot handle 6 volts.

In my opinion, these ferrite chokes do not help much, but placing this glass fibre around the power supply helps a lot. Also a strip of aluminium tape around the cable near the plug.
