## Questions & Answers

**Q: What is the sampling rate of this rf emf meter?**
A: The sampling rate is 1 second. Regards, Omni Controls Sales Team

**Q: Does this measure only at user configured frequency?  i'd like the device to tell me what the max energy detected is, and at what frequency.**
A: yes it does that

**Q: Can this meter be used to measure emf fields in a far infra-red sauna. ideally should be less than 3 milligauss. if so, how do you set the meter up?**
A: No, please note the highest frequency this device can deal with is 3.5GHz, far less than in far infra-red band.

**Q: Is this an adequate and reliable meter to measure RF generated from Smart Meters? Will I need something that measures in the Hz range first?**
A: Yes, This is the best meter for RF generated from smart meters. No, you don,t need anything apart from this meter. If you want to measure signal in power frequency range such as EM field from power line, you have to buy another as this meter will not be suitable for low frequency application

## Customer Reviews

### ⭐⭐⭐⭐⭐ This is an excellent device
*by A***Y on 6 October 2023*

This meter is super accurate, sensitive and easy to use. One month ago I moved into a friend’s house near a powefullv cell phone base station and two weeks later realized that I wake up every morning at 5am, while it is still dark and quiet. I didn’t want to sleep but I also didn’t feel refreshed. This was very unusual for me because I usually go to sleep at 1am and wake up at 9am refreshed. I also got a burnt skin (rash) under my right eye, the side facing the base station during my sleep.So after extensive search on various EMF meters I selected this one, as it has excellent sensitivity (from 0.0001 mW/m2) and is optimized for cell phone frequencies (700-3500 MHz). It also costs much less than other professional devices (which start around 500 gbp).I recommend using two modes: V/m in max setting, and mW/m2 in max avg setting. The first shows how strong the field could be, the second shows your dose of radiation per second. Note that avg setting shows much lower values than current or max, because EMF radiation goes in impulses with gaps between them. So you need to know both the amplitude of those impulses (V/m) and their density (average mW/m2).So first I measured the levels from my phone in various modes (off, airplane, idle, Bluetooth headphones, Youtube streaming via 4g or WiFi), then walked around the city, then finally reached that house. The levels of EMF radiation were through the roof! In a park I got 0.015 V/m max and 0.0003 mW/m2 avg max, and on my pillow 2 V/m and 11 mW/m2! 36666 times more! So I moved to an airbnb with 0.02 mW/m2 and immediately started sleeping like a baby, waking up refreshed, and my burn has healed in a few days.Btw, iPhone gives max radiation when streaming Youtube over 4g with poor signal strength (2/4): 35 V/m and 173 mW/m2 at the antenna and 4.7 V/m and 4.7 mW/m2 at 15 cm from the phone. As you can imagine, levels in this range are not safe, as they were giving me burns and disturbing my sleep. Keep 4G off and use WiFi wherever possible. I also measured my JBL T100TWS wireless headphones and got shocked at their 14 V/m and 1.4 mW/m2 radiation, so I ditched them and ordered wired ones.The only downside of this device is that it supposedly cannot measure frequencies above 3.5 GHz, so it will miss on 5 GHz WiFi and some of the 5G bands, most of which are not mass deployed yet. That said, I am able to measure strong fields from WiFi at my university which operates at 5 GHz, so maybe those specs are super conservative and only mean highly calibrated response, whereas actually it can measure way higher.It will also not measure low frequency magnetic fields such as from power lines, but any smartphone can do that. Finally, this is not a spectrum analyzer, so it will not show which frequencies contribute most, but spectrum analyzers start from 500 gbp and are much more difficult to use. Actually I like that this meter gives a single value summarizing exposure from all frequencies combined, so you don’t need to do any additional calculations, and can quickly measure fields moving around places.Overall, the only thing I would wish for is the (official) support for higher (5G) frequencies, maybe as an exchangeable antenna. Btw, it has 3-axes isotropic antenna, but I still recommend to test different orientations of the meter to find the maximal values. Oh, and it has a lot of additional functions such as alarms upon crossing a preset threshold or storing values in memory, which I haven’t explored yet. The display has illumination for night time measurements.This thing has changed my life. Thank you, Extech.
