Use the Heliognosis EM2 to identify hotspots in your local environment. It is ideal for determining safer distances from electromagnetic sources and locating hidden transmitters. For more information Heliognosis Experimental Report 6: Detecting Electromagnetic Radiation and Minimizing its Health Risks investigates common and less well known sources of emissions.
Our small, sensitive circuit detects the electric field component of the electromagnetic wave and converts it into a visually diplayed signal. Operation is simple - extend the antenna and power on the unit. After activating the power switch, the EM2 will begin displaying the measured electromagnetic field strength. Hold the unit in front of you while approaching potential sources of electromagnetic radiation.The readings will increase as you get closer to the source. Metal objects and buildings will block the radiation. You can use this property to help locate powerful sources located at a distance. If you pass in front of a building and the readings drop, it is likely that the source is behind the building. Driving with the meter on the dashboard or suspended from the rear view meter is an excellent way to survey sources in your neighborhood.
The meter scale has been color-coded to simplify the readings. Blue and green signify low levels of EM where as orange and red are high and potentially dangerous. Newer digital electronic devices such as cell phones, bluetooth, internet routers and smart meters all produce pulsed radiation that can be very strong at times, especially close up. These pulses appear as rapid meter movements and there peak strength can be seen by how far up they reach on the scale.
