4. 3-Axis RF Meter ($199.95) – As you move up the price scale, you’ll notice you get more features and more accuracy. So this meter is a 3-axis meter, rather than a single-axis, like the two meters above. This means that you don’t need to rotate around, but can simply stand in one spot and the meter will scan 360 degrees around you to give you the complete/total radiation level for that particular spot. This meter will also give you the actual radiation level, but again, it only measures up to 30 microwatts/cm2. So if you just want to know whether a spot or room is “safe” this meter is fine, but if you want to know how much radiation above 30 microwatts/cm2 is present, then you’re out of luck (remember, US and Canada upper allowable limit is 1000 microwatts/cm2).
This meter covers 50 Hz – 3.5 GHz – so it will give you readings for most cell phones, wireless computers and cell towers. However, the newer generation of cordless phones and other technology on the 5.8 GHz frequency will not be picked up by this meter. More details here…
5. 6 GHZ RF Meter (Uni-directional $119 + free shipping) – this meter is very reasonably priced and will measure 100 HHz – 6 GHz. It also measures electrical fields (power lines etc.) The only downside is that it is uni-directional only (not a tri-field meter). This means that you will have to rotate slowly in a circle, stopping and pausing at each point to get a measure of total radiation for any one spot. On the other hand, it makes it easy to pinpoint which direction the radiation is coming from! More details here…
6. 8 GHZ RF Meter (Uni-directional $179.90 + free shipping) – This meter is much cheaper than the the Tri-Field below because it only measures radiation coming from one direction, whereas the Tri-Field meter below measures radiation coming from all sides. This meter measures electrical, RF, and magnetic fields as well. So if price is key, then this is a very good choice, since it measures all RF devices (cell phones, cordless phone, WiFi, surveillance bugs, microwave ovens, etc.) from 1 MHz – 8 GHz. More details…
7. 8 GHZ RF Meter (Tri-Field $499 – Ships from USA) – For me, this meter is the best use of my money for what I want to measure. Because I blog about this issue, I write letters to government officials and school admin people, I need to be as accurate as possible and I need to back up my assertions with specific data. This meter is 3-axis (no need to rotate), it measures from .0001 microwatts/cm2 up to 3,000 microwatts/cm2 and it covers from 10 MHz – 8 GHz – so it will measure every wireless device around (including surveillance bugs!), plus leaving room for future technology developments. This meter also measures electrical fields. For the informed layperson (like myself) this is probably the best combination of needed features and ease of use. More details here… I plan to do more blog posts and also some videos showing you how to measure your home, school, office, etc. so be sure and SUBSCRIBE to my blog so you’ll be notified.
8. 8 GHZ RF Meter (Tri-Field, $345 – free shipping) – This meter has all the features of the meter above in #7, but this meter ships from Israel, while the one above is in the USA. So your shipping time is going to be a bit longer on this one, about 2 weeks, but, the great thing is, the shipping is free. I have ordered from this company myself to test and everything went smoothly and the meter arrived in 2 weeks. As I said above, if you want to be able to test EVERYTHING, with ease – because this measures the radiation coming from all directions (tri-field), so you don’t have to keep turning and re-measuring, until you’ve measured a full circle – you can just stand in one spot, facing any direction and it will measure ALL the radiation coming from every direction to that spot – then this is the meter to get.

For people who need to get more specific, there are more complicated meters for this, but of course, they are also much more expensive (thousands of dollars).
