3-Axis RF Field Strength Meter/ English
EN-2 2017-10-25 V002
Introduction:
IM-195 is designed for measuring Radio Frequency (RF)
electromagnetic field strength and the monitor range is from
50MHz to 3.5GHz with triple axis X, Y and Z isotropic sensors.
It is used to indicate electromagnetic pollution generated by
cellular phone tower antenna, wireless internet, microwave
ovens, cellular phones and cordless phones, etc.
With its simple method of operation this meter will measure
electromagnetic pollution generated artificially. Wherever there
is a voltage or a current, electric (E) and magnetic (H) fields
arise. All types of radio broadcasting and TV transmitters
produce electromagnetic fields. They also arise in industry,
business and the home.
Electric field strength (E):
A field vector quantity that represents the force (F) on an
infinitesimal unit positive test charge (q) at a point divided by
that charge. Electric field strength is expressed in units of volts
per meter (mV/m). This meter measures electric field strength
directly.
Magnetic field strength (H):
A field vector that is equal to the magnetic flux density divided
by the permeability of the medium, magnetic field strength is
expressed in units of amperes per meter (A/m). In far field
situations, one can calculate the magnetic field from the electric
field value. This meter can display the calculated Magnetic field
strength.
Power density (S):
Power per unit area perpendicular to the direction of
propagation usually expressed in units of Watts per square
meter (W/m2) or, for convenience, units such as mili/Watts per
square centimeter (mW/cm2).
The characteristic of electromagnetic fields:
