Greenwave Broadband EMI Dirty Electricity Meter

Please read "DIRTY ELECTRICITY" by Dr. Samuel Milham. Then read "EMF*D" by Dr. Joseph Mercola..... Then after that you ABSOLUTELY MUST READ "Invisible Rainbow" by Aurther Firstenburg.... I am an electrician / handy man by day...and a musician by night.....these books changed my life.... And are why I now own this meter. It works really well and being able to actually hear the line noise is pretty cool. Their filters work really well also. Two dropped the Circuit the PC is on from 1800mv down to the low 30s (except on boot up, or when the PC is working hard...then it jumps back up to almost 50). We have all been sleeping much better and did also see a huge improvement in the childrens behavior....not that they were bad kids before...they just don't seem to be quite as...."wired", I guess. If you are worried about EMF and other electrical issues....I also HIGHLY RECOMEND changing ALL of your clothing and bedding to 100% Flax Linen or Whool to help shield you. (very high frequency fabrics, just don't mix the two as they cancel out)

The Greenwave Broadband EMI Dirty Electricity Meter is a MUST if you purchase any kind of dirty electricity filter so you know WHERE to place the filters and how many filters you will need. I also recommend the Greenwave Dirty Electricity Filter as the filter of choice. This meter works very well and is your GO-TO guide for installing these filters. Great tool and EASY TO USE!

I have been buying noise suppression solutions for decades. I have always wondered how many of them were not really doing anything. Well now I finally found out. I have a couple of Furman Power Conditioners (PST-8). I tested them to see if they did indeed lower the noise floor going into my stereo system. Short answer, no. In fact I found that the noises floor on the circuit they are connected to actually went up. These are basically glorified power strips that cost $100. They are for sale now. Basically worthless snake oil. I also tested my Panamax power conditioner (MR5100). This is a lower model in the Panamx range. The Panamax cut the noise floor by roughly 75%. I was shocked. Actual reading dropped from 1300MV to less than 300MV. Actually an improvement and worth the investment compared to the Furman. I recommend getting this device to really know what is happening and to stop guessing and thinking you hear a sound improvement. I am not endorsing Panamax here, just providing the results.

This does detect the "garbage" on the line pretty much line the You-Tube videos. Using the filters, yes it does reduce them. BUT, and the reason I bought them, I was able to prove that for my stereo and HT systems, it makes ZERO difference on the analog outputs. Even the phono stage. Proof that what is needed is a well designed power supply, not some external patch. There is nothing detrimental about filtering out this HF on the power lines. Go for it if you think you need it.

Amazon or the seller refuse to post my negative reviews. Don’t buy this product. It doesn’t work.

Very helpful at measuring the noise level in the home. Watch the video.

This monitor is easy to use - simply plug the unit into any outlet and it clearly shows the quality of the electricity. Once you plug in the Greenwave filter (sold separately) it shows the new electricity "cleaned" electrical number. Once you've got the electricity cleaned, it was amazing how quiet electric devices ran. I highly recommend.

This device works as advertised. It is essential to get a quantitative measurement of the amount of noise that is coming out of an outlet on a specific connected circuit. You absolutely need this tool to be able to establish a baseline measurement of the noise that is on the line for a particular outlet and what the change on the line is at the outlet after applying any treatments you try. This tool was particularly useful for quantitatively showing that several so called "Line Conditioners" for hi-end audio equipment, costing hundreds/thousands of dollars, did nothing to reduce the line noise that was coming out of the outlets from the conditioners! If you really want to know how much noise is on your line and how much, if any, treatments you get to reduce that noise actually worked, you absolutely need this tool, or one like it, to be able to measure the before and after noise difference. HIGHLY RECOMMENDED!

ノイズ対策はオーディオ沼の1つですが、これで可視化することで終止符を打てます。 なんとなく良くなった、なんとなくノイジーでは底なし沼です。 正直自分には高価でしたが、ノイズ対策の判断材料としてなくてはならないものです。

オーディオが趣味で電源関係が音質に及ぼす影響がとても大きいので、汚れた電気を音と数値で検出する測定器ということで購入しました。 使い方は本体に付属の電源コードを挿し込んで計測したい電源や機器や電源ケーブルなどにその電源コードを挿し込むだけです。 とりあえず日用品で使っている電源タップで測定したら雑音とともに950前後の数値が出ていて雑音と数値で明らかに汚れているのが分かりました。 所有しているトランス関連や電源関連などで比較したら性能の良い・悪いがハッキリ出ますし、電源関連が汚れているのか汚れの少ない状態なのか分かるので便利だと思います。 とにかく明るい闇市というショップで購入しましたが、購入してから入荷時期や商品到着までの予定のメッセージがあり、アメリカからの商品出荷後にも運送会社と追跡番号と追跡サイトのメッセージがあったので安心して商品到着を待つことができました。 私の方の設定が間違っているのかメールでは来なかったですが、アカウントサービスからメッセージセンターを開いてメッセージの表示・返信というところから確認できました。 適時、メッセージを送ってくれたので安心して待つことができて、とても誠実な対応をしていただきました。

電源に含まれるノイズを可視化したくて購入しました。本体は小さくコンセントに挿すだけです。ボタンなどはありません。ノイズがあるとザーという音と数値で把握できます。1999mVまで表示でき、それ以上だと1---という表示になります。写真は光城精工のクリーン電源に接続した時のものです。PWMで電源を作っているためメーターが振り切れるほどのノイズが混入していることがわかりました。上の段の1---mVというのがなにもしてない時のノイズ量で、下の段の1084mvというのがノイズフィルタを接続した時の数値です。ノイズフィルタにより73％のノイズが削減できたことがわかりました。このようにノイズフィルタの効果を簡単に確認できます。この表示はコンセントを抜くとリセットされます。また表示部は発光するため機器の裏などの暗いところでも表示が見やすいです。価格も手頃なので1台は持っておきたい製品です。

低価格なのに、他社の高価格の製品で拾えなかったノイズを拾います。
