Metravi EMF Tester

Safety precautions should be taken against electric appliances in places
including medical institutions, schools and residential districts, where
people usually stay for a long time, to prevent patients, babies and senior
citizens from exposure to high electromagnetic waves.
An electromagnetic wave simply means the wave motion of the
electromagnetic field (ELF).
The change in electric fields produces magnetic fields, and the change in
magnetic fields can also generate electric fields.
The fluctuation of correlation between each other is known as
“electromagnetic waves”, which is a form of energy similar to light and
heat that can be transmitted either by radiation in the air or by an electric
conductor.
It is suggested that rearrangements should be made in families and work
locations where electromagnetic fields are detected the strongest in order
to avoid prolonged exposure to excessive electromagnetic fields.

APPLICATION
• This meter is applied to measuring electromagnetic fields of extremely low frequency
(ELF) of 30 to 300Hz
• It is capable of measuring the electromagnetic field radiation intensity that is
produced from electric transmission equipment, power line, microwave oven,
air conditioner, refrigerator, computer monitor, video/audio device and so forth
• The magnetic field unit is Tesla (T), Gauss (G), mini-Gauss (mG) or micro-Tesla (μT)
• 1 T = 10,000 G
• 1μT = 10 mG
• 1 G = 1,000 mG
