1.1 Measuring electromagnetic elds
In today’s world, many industries utilize equipment that generates elec-
tromagnetic elds. Our modern need for communications as well as the
eciency of electromagnetic heating systems and the safety that radar
systems provide us are just a sample of the applications that are benetted
by exploitation of the electromagnetic spectrum. We also have various
engineering considerations as well as regulatory requirements to use the
electromagnetic spectrum wisely. Various authorities have long dened
limit values designed to protect users from the dangers of exposure to
such emissions, and the Nardalert S3 is an eective tool to help companies
and individuals demonstrate compliance.
1.2 About this monitor
The Nardalert S3 (“NS3”) provides virtually everyone concerned with this
subject with an instrument for monitoring non-ionizing radiation that
a body might be exposed to within the frequency range from 50 Hz to
100 GHz (depending on the sensor used). The NS3 has a wide range of
functions, yet it is very easy to use. It also features a handy design, robust
