How does it work?

The Acoutstimeter has a simple design with an on/off button. Once it’s switched on, it will show 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 will primarily be 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 can be heard through the internal speaker.

What frequencies does the Acoustimeter cover?

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

Does This Measure Magnetic Fields?

No, if you require a magnetic field measuring device check out the PF5 also by EMFields
