    Great device for testing safety of your environment
    Gives a fair idea of the levels of radiation in my home and to what extent it is healthy or not. It enabled me to discover that my new Smart TV kept beaming our WiFi radiation even though the menu implied that I’d switched it off. Most Smart TVs eg Samsung, LG, Philips do not allow you to disable this EMF emission. The Acousticom helped my find TV and devices that are safer. Simple to use and quick to identify unhealthy sourced of radiation for my family.

    I think this is the best meter for a general purpose. It measures from 200 Mhz to 6 Ghz which is a very good range.
    The meter is very easy to operate, it shows V/m (Volt per meter) with a display of lights from green to yellow, orange and red.
    The latter is the danger zone and people should not be exposed to this kind of radiation for a longer time. The meter fits into
    your jeans pocket and is inconspicuous and can be taken everywhere. It also has a sound function which can easily be
    switched on or off by just pressing the only button again. This sound function is very impressive as you can hear the pulse
    of the microwaves and from the sound you will know after a while, what kind of waves they are, i.e. from the smart meter
    or the cell phone tower, or the dect phone, or the WiFi, or your cell phone.

    After all the Youtube vids on the subject of Rf & EM fields doing damage in prolonged situations – I guess we just had to find the real truth out for ourselves.
    This device has brought us joy & tears.
    Everyone REALLY NEED’s to get one of these – your eyes will light up at what it reveals about this invisable environment we all live in.

    We showed our neighbours and business collegues what they are living in, and it has shocked every one of them.

    I’ve already written to our local MP with our serious concerns about those Towers & Smart Meters in particular.

    We all need to understand what has happened here, and ‘they’ still want to bring in 5G and much higher radiation frequencies ???? ! in our opinon they have to be kidding us – or should that be killing us! – no way.

    1) We are now making plans to reduce our readings for safety sake.
    2) Get into your router settings and reduce the transmission output to 40% instead of 100% default level.
    3) Got a smart meter – make a faraday cage for it.

    We cant stress this enough – EVERYONE “NEEDS”, NEEDS, NEEDS, This device now!

    I should have bought this a long time ago. I kept putting it off. So far it has been a very reliable little monitor of radiation – easy to use and very accurate. I thought everything in our home was plugged into the wall and we had no wi-fi. The Detector discovered that the TV was in fact on the wifi setting. The monitor went from red to nothing as soon as I switched off the wifi element.

    Very useful – worrying how much EMF there is around

  6. Zimmy Zimmer

    Good little detector it works perfectly,now i know whats all around me its scary

  7. Viktor (verified owner)

    Very accurate and easy to use microwave meter for the price, also quality made and lovely design!

EMFields Acousticom 2 Features

The purpose of the EMFields Acousticom 2 is to provide operatives with an affordable method to take RF measurements in the immediate surroundings and receive warnings. The product is smaller and lighter than the regular Acoustimeter and slots easily into a pouch, freeing up workers’ hands. The EMFields Acousticom 2 comes with several warning options. Users can, if they wish, switch off the audio feedback entirely and rely instead on the LED display. Users can also turn off the alarm in situations where it’s not required. 

The LED display makes it easy to see whether RF levels, measured by V/m, are safe. Green LEDs indicate levels between 0.01 and 0.02 V/m – a level that is okay for most people with electrosensitivity. Yellow LEDs warn users if RF levels go above 0.05 V/m. Between 0.05 and 0.10, some people with ES may begin to experience symptoms. Orange LEDs tell you whether levels have gone above 0.30 V/m, and red LEDs show you if levels go above 3.00 V/m. The top red LED informs you when levels get dangerously high and go to 6.00 V/m. If two LEDs are the same colour, then it means that the RF measurement lies somewhere between the two. 

Different Sounds For Different EM Readings

The EMFields Acousticom 2 wants to be as helpful to users as possible. Because of this, it provides different noise feedback depending on the kind of EM signal that it encounters. The feedback sound for WiFi, for instance, is very different from that of 3G. If you are not currently inside a detectable EM field, the EMFields Acousticom 2 will make the characteristic ‘white noise’ hissing sound. It will also detect a range of other types of radiation, including GSM, DECT, 3G, 4G/LTE, WiFi and TETRA. Each type of radiation causes the device to emit a specific signal that workers can then interpret while performing on the job. 

Highly Sensitive Antenna

The EMFields Acousticom 2 came out of many years of taking practical microwave measurements in the field. The company behind the product wanted to create something that was both user-friendly and highly sensitive.

The EMFields Acousticom 2 covers an EM frequency range of 200 MHz up to 8000 MHz, including the majority of the spectrum used by today’s telephony and electronic communication technology.

Despite its affordability, the device is also highly sensitive, with a sensing resolution of 0.01 V/m. This sensitivity helps to record accurate measurements at a particular point in space and helps to warn people with electrosensitivity that they are too highly exposed.


The EMFields Acousticom 2 relies on taking a rapid succession of EM energy samples. It then processes these samples using the on-board processing unit and uses these to display readings, including the maximum recorded value. It’s worth noting that the device cannot take infinite samples, nor can it display read-outs infinitely rapidly. It takes time for the device to interpret sense data and produce an output. The sampling and processing time means that there could be slight delays between the reading and the output. Sometimes the device will not respond to very short, intense bursts of radiation of fewer than five microseconds. It will, however, collect samples of EM data on successions of pulses much shorter than that – say, for instance, from WiFi signals – and issue a warning based on those. 

Additional Features

  • The EMFields Acousticom 2 is compatible with 9 V alkaline or rechargeable battery
  • There is a green LED light that will turn red when the battery starts to run out
  • The device comes with an on/off switch on the front to press for sound
  • Battery life is ten hours
  • The device measures 110 mm x 63 mm x 21 mm (L x W x D) and weighs 140 g, including battery
  • The product comes with a two-year warranty

How To Measure Signals With The EMFields Acousticom 2 

The EMFields Acousticom 2 offers numerous features to improve usability. The small pouch, display, sound, audio and warning options all help to make it one of the most usable RF measuring devices on the market. 

To get the most out of your EMFields Acousticom 2 you need to use it in the right way. The manufacturer – EMFields Solutions – recommends that you measure sources that are behind the instrument. The current design places the antenna of the device in the upper half and towards the back. This feature means that the device performs best when you present the top rear section towards the source of the emissions, similar to how you would present a contactless credit card to a POS. 

With that said, the accuracy of the device is also high when using the sides of the device, if you find yourself having to measure EM signals from a tight source.
