Product Description

Heliognosis developed the first inexpensive omni-directional broadband monitor for measuring all sources of electromagnetic radiation up to microwaves named the emm. This compact device enabled users concerned about potential health risks to locate areas of exposure. Following the success of the emm initiative, Heliognosis has now released the EM2. The EM2 has several improvements over the original emm including improved accuracy, frequency response and ruggedness. The new design includes a fast response analog display for detecting pulsed transmissions from digital equipment such as wifi, cell networks and smart meters. The included rubber boot is comfortable to hold and elegant while providing protection from bumps and falls. The display employs a unique logarithmic scale to capture both very weak and very strong signals without the need to switch ranges. The color coded scale helps to identify safe from dangerous conditions. EM2 bridges the gap between cheap limited response monitors and full spectrum units. No bigger than a mobile phone, EM2 detects all electromagnetic emitters from ELF (extremely low frequencies) up to microwaves. This includes virtually all sources of electromagnetic radiation like:

RF caution
  • WIFI, cell and mobile phones
  • radio and television broadcast towers
  • AC power lines, smart meters
  • microwave ovens
  • amateur and CB radio
  • military, aircraft and police band radio
  • high-efficiency fluorescent tubes
RF caution

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. 

Using EM2

The 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.
