Acousticom 2 - EMF Meter


The Acousticom 2 is one of the most popular EMF meters currently available

The Acousticom 2 presents RF measurements as an audio signal, with LEDs and an optional alarm at high levels of RF. With simple controls, easy to read results, but still using the same advanced microwave detector as our Acoustimeter, this instrument is perfect for every day use. It comes in its own carry pouch.

Functionality of the EMFields Acousticom 2 EMF Meter

When first turned on the Acousticom 2 is silent. The sound may be turned on and off. It has an “alarm” sounder which emits a pulsing warning at higher exposure levels. If the alarm is not required, then it is easy to disable it each time when you turn the Acousticom 2 on.

The demodulated sounds allow you to determine, with a small amount of practice, what type of device is creating the pulsing microwave levels that are present. These features make the instrument the most useful and practical one available – even for people with severe electrosensitivity.

The Acousticom 2 reacts to very short pulses. Peak readings are what they say – the highest sampled reading – though the sampling and processing rate means that there are some gaps and it will not always react to a SINGLE VERY short pulse(less than about 5 microseconds duration) – though it will react correctly to much shorter pulses that are regularly transmitted (such as from WiFi).

Please note: The internal antenna is at the upper half of the case and the back. Signals are best measured when the source is behind the instrument, but also quite good with the source to one or other side. Turn the Acousticom 2 for the highest reading.

Applications of the EMFields Acousticom 2 EMF Meter

The Acousticom 2 was designed using the experience gained from many years of practical RF and microwave measurements.

LED lights display the peak levels of microwave electromagnetic fields from 200 MHz up to over 8000 MHz (8 GHz), covering the frequencies used by most modern communication systems encountered in our everyday environment. This includes TETRA, all mobile phone systems including 4G/LTE, Smart Meters, and all WiFi and WiMax frequencies.

The LEDs update rapidly, and allow you to quickly gauge the levels in an area and find any hot-spots. Its readout is sensitive to 0.01 V/m. When two LEDs are both lit next to each other, the exposure level is halfway between the two. This is only for levels above 0.1 V/m, e.g. when both 0.10 and 0.30 V/m are lit, the level is about 0.20 V/m (halfway between).

Should I purchase various types of meters?

Yes, we recommend the TrifField® TF2 meter as a great meter for testing all 3 types of EMF pollution: radio/microwave, electric and magnetic. It is especially good at picking up magnetic fields and electric fields. In addition to the TrifField® TF2 meter we’d recommend the Acousticom 2 as this is the superior model for picking up radio/microwave (RF) frequencies.
