Easy to use, the ESI22 simultaneously detects both forms of low-frequency radiation, i.e. the electric and the magnetic fields from 50/60 hertz electric current.
These radiations can be found near power supplies or near practically all devices that work with electricity.
For example, a power line, a computer, a bedside lamp, an electrical switchboard / transformer, a printer, a TV set, an electric oven. The ESI22 allows you to assess your level of exposure and to identify the source, which is to say the cause of the radiation.
