However, this is not a guarantee, and you'll have a hard time getting your issue resolved if you get one of their bad ones! br>br>As a Senior Computer/Electronics Design Verification Engineer now working as an EMF Consultant, I am well-versed in determining whether electronic hardware in general (and EMF meters in particular) is defective, and the GQ-100 is no exception. The EMF 390 I received is clearly faulty (see details below and attached photos). For the same reason, I can tell when a company's Quality Control and Debug processes aren't working: In this case, GQ Electronics allowed a defective meter to be shipped out not once, but twice, they've failed to properly identify/debug/fix the problem on multiple occasions, and they're still wasting my time and energy with ridiculous, condescending, and redundant run-arounds. Instead of taking responsibility for the problem and replacing the broken meter, they use workarounds. Ego? Is it possible that you are inept? Both? )br>br>As you can see from the attached photos (which were also sent to GQ Electronics), the meter I received, for example, shows an RF reading of 0 mW/m2 in both "RF Browser" and "All-In-One" mode. Even when placed next to two transmitting RF sources (cordless phone handset and base station), the device operates in "one" mode. For your convenience, I've included a list of my previously published works. In the same photos, there's a good Cornet meter that's set to the same units and readings the right way. One would think that this would be sufficient proof for them to recognize the issue and accept responsibility for doing the right thing by their customer who had debugged and verified the issue for them. Surprisingly, however, this isn't the case. br>br>When I returned the broken meter, they said it was "user error" because it was in mW/cm2 units (which I tried as a last resort because it only ever read 0 RF in mW/m2). The meter has never registered an RF signal, as I've repeatedly told them. In all RF-sensitive areas, it displays a value of 0 RF. Detecting modes, orientations, and units in the presence of RF radiation (cordless phones, wifi, mobile phones). However, they simply ignored me and lectured me on the differences in unit settings (mW/m2 vs. mW/cm2) and returned the faulty meter to me without even testing it (of course). br>br>Now, despite having seen the photos, they've turned down my second request to return the still-in-use camera. Meter that isn't working. Rather than giving me the cold shoulder, you've decided to give me the cold shoulder around. stating that due to the sensor's location, I should experiment with different meter orientations. Not only does the meter read 0 RF in any orientation/units, as I've told them multiple times, but if one of their "working" meters can't accurately detect an RF signal right next to TWO TRANSMITTING RF SOURCES (cordless base station and handset - see below), then the meter isn't working. if you look at the pictures), then it's pointless: If one of their "working" meters works like this, your health is in grave danger if you rely on the GQ-100. EMF 390. But, I believe the meter is truly defective; they simply refuse to admit it, and this is just another pointless and redundant run-around. around, wasting more of my time and energy, avoiding the problem, and leaving me with an RF Radiation meter that is useless. br>br>And while we're on the subject of ridiculous and redundant run-on sentences, arounds: "Are there any possible firmware fixes I could try before sending it back?" I asked the first time I called in after being told I needed to return the meter. "No, it's a hardware issue, and you should return it," Joseph explained. "br>br>Now they're asking for the serial number as well as the firmware version. implying that a firmware update is required. First and foremost, I checked this when I returned the meter (at my request). Second, why didn't they double-check this before dispatching a meter in the first place? and, more importantly, when a meter is returned? (Again: Debugging methodology and Quality Control practices are both broken. not to mention the lack of professionalism and ethics. )br>br>As a result, you can expect nothing but headaches and unethical, buck-passing behavior. a run-through If you get a defective meter from GQ Electronics, you'll get a bunch of freebies. They will not do the right thing by you by accepting responsibility for the problem and resolving it. Instead, they'll point the finger at you and waste your time and energy avoiding you. I regret ordering it and hope to warn others about the dangers of having a similar experience if you order one of their meters. br>br>My dealings with GQ Electronics have left me enraged, frustrated, and dissatisfied - Beware!.

I looked on the website for a better manual, but all I found were for other models, not this one. One thing I don't want it to do is automatically rotate the screen when I move it slightly. When trying to read the display, it's extremely inconvenient! (An email from the company informed me that the rotating display is known as "swivel" and that the auto mode can be turned off. ) They also sent me a link to the proper manual, which is in PDF format and easy to read. That fifth star is now theirs! br>br>I worked as a radio communication technician for 35 years, so I'm picky about how test equipment works. However, it appears to function as advertised. In my neighborhood, there is an 800 megabit (30 channels trunked) state police radio tower with microwave dishes strewn about. My house was not in any strong RF fields from the tower, according to this device. (A friend who lives much closer lives in a terrifying 24/7 RF bath. )br>br>This unit did a good job of picking up power line EMF, which is the biggest problem in my house. The Dell computer tower under my desk (which was essentially radiating EMF between my legs) was a major source of EMF and had to be relocated. My bedroom computer is a more powerful Dell that emits almost no radiation. My WIFI was well placed, but if your WIFI is close to where you sit, move it at least a few yards away (the RF field around the WIFI box is quite strong). (low-quality LED and more industrial home/office florescent lights may surprise you with how much EMF and RF they emit)br>br>I'm not convinced this unit is capable of picking up the intermittent pulses that an idle cell phone sends. The meter does respond, but because they are pulses, the meter averages them out. If you or a child sleeps near a cell phone, check or measure the phone's RF output while it is on a call. It pulses out the same amount of power (which isn't healthy; pulsed power is actually worse for you than constant power). Will this work on 5G? br>br>Can you tell me if it will work on 5G? Although most 5G signals will be above its operating frequencies, it should be able to detect constant pulses as rf or EMF. (With its constant "milometer" wave frequencies and constant digital modulation pulses, 5G has no redeeming qualities. ) if you lose that fight (and you will lose) ,,,MOVE or try to shield yourself from 100% area/busines saturating signals . By 2020, it is expected to be up and running across the country!.

GQ EMF is one of my favorites. Due to the following factors, 390 has been assigned to it: It displays all types of EMF on a single screen, allowing me to quickly determine which are in danger. It analyzes each signal's change in realtime, but I'd give it five stars if it could detect 360 degrees like a well-known brand of EMF detector. The signal is only visible when the device is pointed directly at the EMF source; otherwise, the signal is very weak. So, if you're looking for a potentially dangerous EMF source, remember to scan it from all sides.

The addition of a channel spectrum analyzer is a huge plus. Yes, it isn't as accurate as professional-grade meters/equipment, but it's a great little device for checking your home, even if only as a rough estimate. The LCD on the first unit I received died after a few days, but they quickly replaced it with a new/repaired unit and shipped it to me within a week. Check your laptop, cell phone, cordless phone, microwave, and anything close to your bed (including an alarm clock that was emitting an excessive electromagnetic field near my wife's head) with this meter.

I was able to tell how much EMF, EMF, and RF radiation was present in my bedroom at night using this tester. I also bring it with me on trips so that I can detect radiation in a room and either unplug the emitting unit or cover it with a copper-coated cloth. A sheet of silver br>This is a product that I strongly recommend.
