Which meter is best?

I hope I can get a meter that will check almost all things that I need to check for EMF/RF. I now have a trifield and a stetzerizer. Someone on this forum (found in a search) mentioned that the Hf35C was a good one. It was about $300 last week but is now $310 approx. Is that the best in that price range and will it check a wide range of fields. Also, I know that Lloyd B. has reviewed the acousticom2 and cornets. I want to check my computer, monitor, mouse, cell phones, and wifi. We have wired 'smart meters' and I understand that that is worse to get away from than wireless. Do y'all find that the stetzer filters work for dirty electricity. It seems that all the experts believe it does, like Magda Havas, etc. One more thing I wonder about...I can't think of the name of it right now but it was called 'something stick' and the stick was just something you attached the meter to and it could detect bad spots in the walls and pipes. I think it was just about $20. Are they worth it for what they do AND will they detect underground currents?
I just would like to know what anyone has had good results with and if everyone thinks any certain one is better than others. I may have really shown my stupidity, but I can't keep it under wraps forever. Any help is greatly appreciated. Patsy |

I use and sell the CORNET ED88T which can measure both RF (100MHz-8GHz) , ELF magnetic Field, and ELF electric field.
In all modes it shows the current measurement and the Max level measured. In RF mode it shows also the Frequency of the largest signal, the average over 15 seconds. In RF mode it also have audio feedback and settable alarm. And all for less than $200 (189.9) For more info and video please see- http://www.4ehsbyehs.com/emr-meters/cornet-ed88t amirb

Hi Patsy,
Yes, there is a lot to learn!
The HF35c is a great meter. Every meter has advantages and
disadvantages, but this is the one I go to when I do RF
measurements.
Yes, Stetzer filters actually work. You will be able to see
this when you measure with your Stetzer meter.
The Buzz Stick is useful for locating sources of AC magnetic
fields... but you already have a Trifield meter which can do that. There is no
meter which can be used on the surface to detect underground
currents.

The Hf35C is not a stand alone meter. Avoid. It has only a limited set of frequencies it detects. I have one and bought it for find direction of transmissions only. It ignores most wi fi. I have no idea why Emil would praise it as a stand alone meter. I have huge wi fi front and back of my home and this meter does not pick it up...because it only goes up to about 3GHz
I'd go with a cornet. I have an 85. However even tho it says up to 8GHZ the lessemfpeople tested and found it only goes up to 6ghz. I'd avoid a cornet with a built in gaussmeter as it is difficult to find your way around all of the options. I recommend 85. I have not investigated the 88. |

I have most of the meters on the market, even a number of spectrum analysers.
But the meter I love is the Esmog Spion. When I am going for a house survey, the first thing I do, is take the Esmog Spion from my car door and listen to it, without any antenna pulled out. That gives me a good impression what is going on. Furthermore, by prssing a button, one can measure LF. For that the telescopic built-in antenna has to be retracted. It can also measure what I call *dirty air*. www.priggen.com/Esmog-Spion-Inexpensive-Broadband-Receiver-for-Electrosmog article: 90150. 238 Euro ex VAT. |

I have an HF35C which is excellent at detecting Wi-Fi. Does your meter show any read at all when in the presence of Wi-Fi or does the screen go blank and only show a 'one' on the far left of the screen which means that it has maxed out its 2000 uw/m2 capacity? If the Wi-Fi is so strong that it maxes out the device, purchase an attenuator or more to double, quadruple, etc., its capacity.
The Cornet ED78S does ignore some Wi-Fi unless it is very strong (in fact, the instruction sheet that came with the Cornet states that Wi-Fi is of no concern!) , so I depend on the HF35C for getting a good picture of what's in the area. It is not calibrated to measure under 800 uw/m2.
Perhaps your HF35C is defective? It does not measure magnetic fields - a gauss meter is needed for that. From: Lynnezhu [via ES] <ml-node+[hidden email]>

@ Patsy - By 'wired meters' do you mean that you have power line communication (PLC) digital electric meters? There are two types of PLC used in the US - either TWACS (two-way automated communication system) or Turtle Hunt TS2. Do you know which one is used by your power company?
TWACS is considered the worst but I've read testimonies of people affected by Turtle (some Turtle meters are still AMR and send information only one-way which may be less problematic and may do it infrequently instead of constantly) since the radiation is coming from all the wiring in the house from the pulsed RF added onto the 60 hertz sine wave making it an unintentional radiator. TWACS is a hybrid wired/wireless system designed to communicate with wireless gas and water meters and eventually a HAN device which the utility will bribe customers to install in their house, because most utilities have added a UMT (universal metering transceiver) inside the TWACS meter. Good luck finding out the information from your utility provider as my power company has shown themselves to be either ignorant or liars about the 'smart' technology they're using.
From what other ES have told me and my experience is that Stetzer filters will not help at all with PLC DE (dirty electricity) because those frequencies are not in the range of frequencies which a Stetzer can filter out. If you should use a Stetzer make
sure you take magnetic field reads before and after installation because if that outlet is on a circuit which has been wired incorrectly (over 90% of homes have wiring errors) the Stetzer will create a massive high magnetic field throughout the house. I found
that out the hard way and will never use one of those filters again. From: Patsy [via ES] <ml-node+[hidden email]>

Fog Top, I don't know which kind I have. They were put on my house in 2009 but I didn't know about it until two years later. I called the utility company and they told me they were not wireless and they meant for me to think they were harmless. I didn't believe it then and have since found out that they can be worse than wireless. I have just recently heard of TWACS. Has that kind been around for a long time? Do I have to try to find out from the utility company or can I tell by looking at the meter or testing. When I first got my trifield meter, I tested the 'smart meter' and it pulsed about every 20 seconds I think. Does that tell you anything? I will research the info on TWACS. It really helps to know what is important to try to learn more about. Thank you so much.

Thank you all for your knowledge about the meters you like and use. I want to get the meter asap, but I also want to be sure to get what is right for me. It will take a little longer to be sure. A meter will help me to be able to find out how any kind of shielding fabric checks out with the meter so I can begin to get protection. I may have more questions. This forum is great and all of you are so helpful. I am 73 years old and I know the EMF's/RF's have harmed me and I am hoping that if I get proper shielding it will make a major difference in my health. I want to thank you every one for your advice. I will let you know which meter I buy and how I like it.

If you see it pulses every 20 seconds, it is a smart mash RF meter. not PLC or other.

this is the frequency measure of the HF 35C meter, copied from the lessemf.com specs
true logarithmic - periodic antenna, 800 MHz – 2.5 GHz, single polarized, included much is beyond 2.5 ghz. fwiw I use the little canary wireless to detect wi fi fields. it misses some but it extremely useful and convenient. not a stand alone however as it only measures wi fi. |

In reply to this post by Fog Top
In my repeated experience the hf 35c does not detect all wi fi. My cornet is better but the canary wireless detector is also helpful. You could also just take your laptop to an area and set it to find wireless networks...
This limitation in frequency detection of the HF 35c is also detailed I think in Lloyd Burrell's analysis of it. If you are using it alone good chance you are missing some of the most powerful new wi fi imo. The two wi fi networks which are causing me to have to sell my home (!) are not detected by the hf 35c.. I think they are At and T uverse internet. the screen does not go blank or show a 1. I am not using it as a gaussmeter... Correct me somehow if I am wrong...as there is a big discrepancy here. I think there is some device you can get with the HF 35c to extend the range? Maybe you got that and I didn't? |

EXTENDED RANGE HIGH FREQUENCY METER
Just like the High Frequency Meter above but examines 27 MHz - 3.3 GHz, with residual sensitivity to 6 GHz. Includes both a directional and an omni-directional antenna. Model HFE35C. Extended Range High Frequency Meter (Cat. #A483) ........... Was $895.00, On sale now, only: $795.00 add to cart this is from lessemf.com catalog. |

The problem in measuring WIFI is not the frequency but the short burst nature of the signal.
Every pules in WIFI is very short in time, sometimes shorter than 1 mS. In order to detect it (not measure) you need a fast meter with a high sampling rate. The CORNET ED78 samples 3500 times per half a second . The CORNET ED88T samples 5000 times per half a second. Both show the max level measured in the last half second. this is much higher then other meters that are out there and is the main reason to go for the CORNET meters. In addition the CORNET has a very informative display with lots of information , specially the ED88T, and is relatively easy to operate. I have also a GIGA HERTZ HF35C, ACOSTIMETER AM10, CORNET ED85 and other meters (all very good) ,but the ED88T is the best value for money and the ED78 follows. I hope this info helps. amirb

@Patsy - do you own a camera that you can upload pictures to your computer with? If so, I'll contact you privately with my email if you want to forward a picture of the meter to me. Sometimes a picture will tell what system the utility is using but GE & Landis Gyr make both wireless and PLC meters. All new Itron meters that I've seen have been wireless.
You may have an older AMR (one-way communication) meter. I know an ES lady who recently moved into a home with an older AMR PLC meter and she says she feels OK but hears buzzing noises often.

The more one experiments with the diverse hand-held meters on the market, the more clear it becomes that these are all both limited in their scopes and not delivering on the given specifications.
This applies even to the expensive Spectran meters i tried. My Accousticom-2 has problems dealing with dense emf-environments and with certain signals, but it is useful and user-friendly, especially in the countryside. My Cornet ED75 broke down, and even destroyed a rechargeable battery as it did not shut down on its own. The Gigahertz meters appear reliable and to remain that way. Nothing seems to beat the old Esmog-Spion. Try to catch the emf from a mouse, a keyboard, a monitor, a phone-cable, a video-cable etc. with a bunch of meters and if the Esmog-Spion is among these, it will most likely turn out to be the absolute winner without much serious competition. The Trifield is cheap and probable a good meter as a start, in order to find the worst offenders within ones house. I like analogue scales and may get one, as well as a Trifield-Natural-EM-meter. Concerning Stetzer-filters you may want to read : http://www.conradbiologic.com/articles/EMFscams.html http://www.emfrelief.com/capacitive-filters.html "So a capacitor filter, by whatever name, will Not make your electricity cleaner, but dirtier." Electro-sensitivity is an extremely individual matter, which can be usually much better be felt than measured, as no meter knows for which frequencies and combinations of frequencies one is vulnerable at a given moment. Our own sensitivity is potentially much more refined, complex, individual and intelligent than any dumb meter, and it's free and always at hand. |

Fog Top, I appreciate your help on the smart meter. My husband and I aren't too good on electronic pictures but I know we can do it. I'm just not too sure how soon I will get back to you on that. That will be a big help and I also want to learn about those different types of meters you named. Thank you.

Everyone has been so helpful for me to make a decision on the meter. My husband decided to go with the cornet 88. They all sounded good. We needed it to not be too complicated. I love this forum and do a lot of reading of the archives. I am not sure I am doing this to reply to everyone at once. Thank you all so much.

The ED88T can display the strongest frequency up to 2.7 GHz, which is worth something.
However between 10 kHz and 100 MHz it is not supposed to measure or detect anything. Likely it's worse than this, as manufacturers tend to exaggerate the performance of their products. Hopefully CornetMicro will come up with a meter that covers the missing range also in the near future. Noteworthy is here that the ED85EXS does only measure from 1 MHz upwards with special external antennas, with the standard antenna the lower limit is about 700 MHz, which is worse than the ED88T, that has a fixed and compensated internal antenna. The Esmog-Spion is actually the only allround meter now that i know of, although it is not designed to catch the new wifi in the 5 GHz. Well, except for the EM2 from Heliognosis, but this one fails nearly completely when exposed to the common 50 / 60 Hz. It looks more as a toy for children but is still a bit useful for testing monitors for instance, for which the Cornets and most other meters are of almost no help due to a limited frequency-range. The Trifield 100XE and Trifield EM together also should be an allround combination, apart of being not very sensitive, and useful to localize and judge sources of EMF within ones house. Important to remember is that the electronic parts in EMF-meters can be damaged by extremely strong fields. Therefore, take care not to hold it totally against ( touching ) mobile or dect phones, the antennas of wifi modems and so forth. A distance of 15 cm / 0.5 foot should be fine ( if i'm not mistaken ), the safe way to play it is to remain under the upper boundary of the scale of the meter. The Cornets can switch on unintended in ones pocket, as the power-button is huge. Mine broke down after i forgot to turn it off once, which caused the voltage to drop to zero. So it is not a well-built, solid device, but I would buy an ED88T for price the middlemen get it ( 98 $ ) at http://taiwan.cornetmicro.com/ ;(. |
