How good or accurate would this be for measuring the amount of EMF coming from my home wi-fi router??

Never tried it on my router ! But 5 bars in front of a microwave. In order to get to green you have to stand about 5 feet from microwave before it is EMF free.

It only measures current (not voltage, not power factor) and calculates kW and kW-Hr from that so it's not the most accurate tool for the job. The reports and stuff are good enough to do that, if you can live with perhaps 10% accuracy.

Definitely less than that. Currently it is having trouble picking up on the Wi-Fi in my home. I bought another adapter by HornetTek that is working much better although it's a bit bulkier. I believe my HornetTek adapter is supposed to get up to 300 or 400mbps. Remember this is just an estimate of speed the adapter can take in. It really depends on the speed of the Wi-Fi you are using.

I.m not sure why you specifically mention relays on vehicle air conditioners, as if that would take a special meter. However, this little inexpensive meter does have the ability to measure volts, both AC and DC, ohms, amps, check capacitors, diodes, do a continuity check, and resistance checks. So, depending what you are wanting to check, I think it would serve the purpose just as well as a more expensive one, if you are worried about cost. I really don't know what else you would need for checking a relay, whether on a vehicle air conditioner or any other piece of equipment. Most of the time you either want to know !. is it getting power, 2.are the points open or closed, 3. is the power getting across the contacts, or 4. is the relay coil burned out or not. So yes, I think this would do what you want it to do, and for a good price. For home use, or a DIYer, this is a good little tool.

From what I understand, the product doesn't work by changing the EMF levels in the environment, so a meter would not show anything. It is supposed to work by helping your body to dissipate the harmful EMF frequencies by grounding you (and others in the house) into the electromagnetic field of the earth.

You are looking at a low-frequency EMF meter. It measures EMF from mains electrical devices and other (very low frequency) EMF sources. You can use this type of meter to check EMFs from mains electricity, power lines, high voltage lines, electrical installations, sub-stations and transformers, house wiring, domestic electrical appliances TVs, computers, office equipment, factory machinery, vehicles (cars, trains etc). This meter is not designed to measure ionizing radiation (x-rays and gamma rays), or radio-frequency / microwave radiation, unless specifically stated.

I do know it measures the EMF radiation from Wi-Fi. I do not know the technical specs, however when I tested it in my living room (which faces the neighbor's smart meter) - the beeping on my Cell Sensor EMF Detection Meter just went to the highest danger level. Hope this helps.

Actually the amount of EMF in microwaves are not small, they are very high, over 200 micro gauss near the microwave front. This equipment can detect it, but the whole amount of EMF is not showed.

No, I think. It's max range is 10. GaussMaster is used to measure the magnetic field produced by electrical power lines or other home appliances. I used it to measure the frequency near TV, microwave, and the high power line goes through the backyard. Really useful in indoor and outdoor. It measures in two modes; 0.1 to 1 for small frequencies (power lines) and 1 to 10 for higher frequencies. Microwaves and TVs produce in the range of 50s, you would notice the needle hitting the right.

I tested it against other emfmeters.No documentation is available. I suppose it measures V/m for low frequencies waves, not. radiofrequencies.It worths price se paid!

You might want to check with the seller. I have the EMF Shield but I have never measured changes in EMF levels. If you do get the EMF Shield and measure, I would be interested in seeing what your results were like!

Yes. This meter is very sensitive. I will detect the signal from an individual cell phone or a nearby tower. It is particular useful when setting up wifi to make sure you are using the lowest power setting, and locate the wifi transmitter away from people.

I've used the MS2108 to measure 12vdc parasitic current on my RV. Not sure of the overall accuracy (don't have another meter to compare with), but it did seem to be reasonably stable down to 100ma (only used the clamp-on function). I didn't make any measurements less than 100ma, so I can't comment on measurements less than this.

Hold it to where it does not go off and move it towards a power cord or a fluorescent light. It should go off the closer to the power it gets. It does not tell you if it is measuring EMF or RF energy.

I don't think any clamp-on inductive style ammeter is going to be that accurate. Even the really top end ones are probably +-0.2 amps or so. You need the type that has actual wire connections.

Yes, it measures EMF from anything. If I set the meter to EMF and then put it down next to my cell phone (an Android), I see the meter increase as the meter gets closer to the phone. I also see the meter spike off the chart from time to time as the phone emits bursts of power for this and that. That's true for most anything that uses electricity, including other screen-based devices (monitors, etc.). The contradicting answers that you are seeing are probably because there are different types of waves to measure and different phones have different emissions; this device measures micro/radio waves and EMF. This device did measure micro/radio waves for my phone when I tried it, but I don't know if it's measuring the full emissions of the phone because the level registered when I did a test was very small (I put the meter down next to my phone and dialed another phone and stayed connected for a while). However, I haven't seen any consensus among scientific studies that those types of cell emissions are dangerous, whereas-though there is still some debate-some studies agree that high levels of EMF (around or above 4 milligauss/.4 microteslas) increase the risk of certain childhood cancers.

Personally I did not find it capable of detecting frequencies in the MHz itself let alone GHz range of wifi. It is best for detecting ELF such as power lines and microwaves, but that's about it.
