Let me start this review by saying that I will never recommend this meter. I'll explain why below if you're interested. In summary, he does a lot, but little is well done. Now I have 5 meters. 3 of these are professional gauges that I use to evaluate clients, 2 of which are amateur/toy gauges (GQ-390 is one of them). I got my education. I've been studying the biological effects of EMF on the body for about 2 years and have been doing home consultations for a little over a year. Several professional training courses, a lot of self-education. Good. As if? - This meter, the GQ-390 EMF Meter, has a lot of bells and whistles unheard of for someone like me in this price range, so I made the investment and decided to try it myself. Let me just say that this counter UI is the best I've seen. I've seen it never crash, it does what you want it to do, and generally it's easy to read and navigate once you've used it a bit. Build quality is satisfactory, but don't expect much from such a cheap meter with so many features. It detects electromagnetic fields, especially electric and magnetic fields, with reasonable accuracy. There were times when I got identical readings with another similarly priced meter (Alphalabs TF2) that is known to be reliable for electric and magnetic fields but TERRIBLE for HF. The HR readings on both of these devices are inaccurate and VERY inconsistent when compared to third-party lab-certified, professional-grade meters like the safe and reliable Pro ii HR meter. It's not complete rubbish, it's just not very good at what it's trying to do, which is why, as a professional, I would never advise people to use it, other than that it's just a toy and something to play with. I would never take these testimonies legally, or at best I would take them with a grain of salt, knowing that you are only getting a thin slice of the full picture they are supposed to be revealing to you. Here's the bad news. - I wanted this gauge to be big. I wanted him to fulfill his potential. The main problem arose from three main problems I encountered as an EMF.1 security specialist. Accuracy. With third-party tested and certified gauges, this GQ-390 just doesn't pay for itself. Evidence is conflicting, exaggerated, or not sufficiently exaggerated. There were times when I couldn't get a reading while standing 3 feet from a shielded router. I've tried this with several router models.2. Range - Testing in the 6-10 GHz band, I couldn't see any results with the "Radio Frequency" setting. This is worrying because this meter has shown me, particularly when deploying the 6 or 6GHz WiFi radio bands, that the radiation from these routers will be invisible, giving people a false sense of security. It ALSO refers to micropulses per second. what this counter can detect (something the cheapest counters are not good at). This treats smart meters and Bluetooth as normal sources of very narrow RF micro-pulses that most low-level meters cannot detect. Again, this gives people a false sense of security, making them think they have low readings in the immediate vicinity of their Bluetooth devices, smart meters, or other devices, when in fact they are exposed to potentially dangerous RF levels.3 . Half-truths about GQ Electronics Marketing. A half-truth is always a lie. If you don't fully disclose what the meter is capable of and endanger people's health, I don't want to support you financially. You are not someone I would NEVER refer clients to. This counter is nothing more than an overpriced promising toy that doesn't quite live up to the claims of the companies. I prefer the truth for profit in business. Tell people what this meter can and can't do. Let them feel confident about their purchase instead of hiding what they are really investing in. Summary #2. To sum up, if you've gotten this far, don't buy this counter. Don't trust the testimony he gives. Until they test every meter from a third party and ship it with a meter certification capable of doing what it claims, I will never tell this meter to my customers or anyone seriously trying to read EMF in their area to invest in them.
