Acoustimeter EMF Detector FAQ

The EMFields Acoustimeter AM11 is one of the most popular EMF detectors in the market. The Acoustimeter is easy to use and an incredibly powerful radiofrequency (RF) / microwave detector. In this post, we will try to respond to the most frequently asked questions about this EMF meter.

How Big Is the Acoustimeter?

The Acoustimeter is 190 x 102 x 33 mm (LxWxD), meaning that it’s easily transportable.

How Does the Acoustimeter Work?

The Acoustimeter has a simple design with an on/off button. Once you switch it on, it shows the readings (whether they are audible or visual) on the LCD screen. The internal state-of-the-art antenna is located at the top of the device, allowing for a more accurate reading.

The signals themselves are primarily measured when the device is situated behind the instrument, but it also has the capacity to measure sources when they are located to the side. If the source is placed in front of the EMF meter, the LCD will perform like an RF screen.

How Is the Sensitivity Displayed?

If it’s a peak display, it will appear as a figure between 0.02 V/m and 6.00 V/m. If the source is giving off an average display, the sensitivity will appear between 1 µW/m2 and 1000 µW/m2.

How Is the Pulsing Signal Heard?

It IS heard through the internal speaker.

What Power Source Does It Require?

The Acoustimeter is powered by 2 x AA alkaline or rechargeable batteries that have 1.2 – 1.5V capacity. It draws 105 mA at 3V.

What Frequencies Does the Acoustimeter Cover?

The Acoustimeter EMF detector displays the peak levels of microwave electromagnetic fields from 200 MHz up to over 8000 MHz (8 GHz).

What Fields Does It Detect?

The Acoustimeter detects radiofrequency fields.

What Are Peak Readings?

The peak readings are what they say on the tin – they are the highest possible reading. Accurately and efficiently reacting to shorter pulses that are frequently transmitting (e.g from WiFi), the EMF meter is ideal for those in any industry. However, it’s important to know, that the meter won’t react to every pulse – in particular, those that emit for under 5 microseconds.

The peak-hold reading shows on the LCD screen. This can be higher for particular sources, but because the peak LED display doesn’t show all pulses, it can be difficult to detect. If you want to try and detect the peak-hold, you can simply turn the device on and off again and the previous reading will clear.

What Are Average Readings?

The average reading will calculate the average amount of RF levels by updating 4 times each second. Giving you a more accurate result, it will consider RF levels that are far lower than other sources (I.e WiFI and DECT – which has an average power of 0.01). Translating the highest peak reading into true average power, you will be able to measure the levels far more efficiently than when you use an outdated emf meter.
