AC Electric Field MeasurementsHome pollutants

Wherever there is AC voltage, there is AC electric field which can be measured in V/m.

Our calibrated EMF testing equipment cover a wide spectrum range;  from 5Hz to 1 MHz:

–  Low-frequency analyzer ME 3851 A   Freq. range: 5 Hz  –  100 kHz     Measuring range: 0.1-1,999 nT

– 3D-LF analyzer with data logger NFA1000  Freq range: 5 Hz – 1000 KHz

  Four Demand Switches (NA7) installed in the switches box to cut the AC power automatically from circuits at no demand, thus eliminating the EMF from sleeping areas in particular.
