The Scalar devices will emit EMF as RF also. If you measure it will show a quite powerful field. Now, the difference rests on the fact that the Scalar boxes generate a field that is made of coherent energy. Is not incoherent and chaotic as the type of frequencies that electronic devices produce. Even your electric installation in your house sends electromagnetic frequencies that are chaotic and detrimental to any living organisms. The AC unit, your Fridge, the router, TV, cell phone and so forth. You will be reading EMF and RF in the field but the difference is that this energy is coherent and not chaotic. Not all EMF or RF are detrimental to living organisms. What is detrimental is the chaotic frequencies and the Scalar devices are coherent.
