Safe and Sound Classic II

For measurement of wireless frequencies

The easy-to-use EMF meter for everyone

For anyone that even suspects, or is an electro-hyposensitive (EHS), then it is essential to know what levels of electrosmog you experience in your everyday life. This meter is incredibly easy to use (you simply switch it on!).
Its output and display is meaningful to all because it uses a traffic light system: green, orange and red. This corresponds to no, slight, severe and extreme EMF exposure levels (See image 4).
This meter is a significant improvement on the already excellent Acousticom II (no longer available).

The product is engineered with aerials that pick up frequencies both vertically and horizontally. The meter is able to detect very short pulses as for example, emitted from smart meters. Typically, other meters in this price range will miss these short pulses.

We’ve been delighted to use the Acousticom II for 15 years, and we are so pleased to offer its natural replacement. This is the go-to basic meter for beginners and experts alike due it it’s portability and ease of use.
