But again, if you don’t care about the details and budget is key, then this one may meet your needs.
This meter covers 50 Hz – 3 GHz – so it will give you readings for most cell phones, wireless computers and cell towers. E-Alert Meter ($29.95) – Another really simple RF meter – but like the one above, this one also measures magnetic fields, which is either a beneficial feature, or a confusing one – depending on your needs.
However, the newer generation of cordless phones and other technology on the 5.8 GHz frequency will not be picked up by this meter. This one also does not give actual readings, but just has different colored lights: green-safe, yellow-caution, and red-unsafe.
Also like the one above, this one is only a single-axis meter.
It is also really small (keychain sized) only 1″x3″ – which again, may be a positive or a negative, depending on what you want it for. This one only measures up to 58 microwatts/cm2, so same problem using in North America where our upper “safety” limit is 1000 microwatts/cm2 – you’ll know it’s unsafe, but you won’t know how bad it is.
Also like the meter above, this one is only single-axis.
If you want the full-service radiation meter, so that you can measure everything in every situation, from one spot, then the Tenmars 8 GHZ RF Meter (3-directional, 5 free shipping) is your best choice.
Here’s an In-Depth Description of the Various Radiation Meters and their Pros and Cons: 1.
Simple Radiation Finder (.95) – this is your most basic digital RF meter.
It will not tell you the exact level of radiation, but will simply light up a warning if the radiation falls at pre-determined categories of green-safe, yellow-caution, and red-unsafe.
