The Acousticom 2 by EMFields is one of the most popular EMF meters currently available. The device displays the peak levels of microwave electromagnetic fields from 200 MHz up to more than 8000 MHz (8 GHz) and is backed by a two-year warranty to give you peace of mind.
The Acousticom 2 uses one 9V dry alkaline battery
The Acousticom 2 has a single on/off button for all operations. Once the device is switched on it will begin providing both visual and audible readings.

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.
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.
