Rent Narda ELT-400 Magnetic Field Meter

The ELT-400 is an innovative exposure level meter for measuring magnetic fields in the workplace and public spaces.  It is designed for health and safety professionals in manufacturing, the insurance business and the service industry.  This instrument handles virtually any level measurement in the low and medium-frequency range, simply and precisely.  It is comparable to sound level meters commonly used in noise assessment at the workplace.
Production Area
The ELT-400 is ideal for use with diverse manufacturing machinery, including induction heating, melting, and hardening equipment.  Also, due to the extremely low frequency limit and high power capability, most magnetic stirrers can be measured.  Special demands often occur with machinery in production areas where non-sinu-soidal signals are common, e.g., in industrial applications that use resistance welding machinery (pulse waveform, phase angle control) with traditional 50/60 Hz systems as well as in newer medium-frequency switching units.
General Environment
In public spaces, complex fields occur with several kinds of electronic surveillance systems.  Most of the electromagnetic and acousto-magnetic gates are operated in the frequency range of the ELT-400.
EMC Test House
Magnetic fields generated by household appliances or other electrical devices are receiving increased attention.  Some new standards such as EN 50366 (IEC 62233) describe how to evaluate such products.  The ELT-400 is the ideal measuring device for compliance with these standards.  Benefits include the perfectly matched frequency range and implementation of the specified transfer function.
