The Narda ELT-400 is an innovative exposure level tester developed for measuring magnetic fields in the workplace and in public spaces. It can handle practically any level measurement requested in the low and medium-frequency range, simply and precisely.

The Narda ELT-400 performs direct evaluation of field exposure in relation to major standards and regulations such as Directive 2013/35/EU for workplaces. It also performs automatic exposure analysis for various waveforms in compliance with weighted RMS and weighted peak methods and eliminates the overestimation that occasionally occurs with FFT-based evaluation. This tester is IEC/EN 62311 and 62233 standard compliant.

Production Area
- The Narda ELT-400 Exposure Level Tester is useful with diverse machinery used in manufacturing. This includes induction heating, melting and hardening equipment. Also - thanks 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-sinusoidal 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 article surveillance systems. Most of the electromagnetic and acustomagnetic gates are operated in the frequency range of the Narda 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 describe how to investigate such products. The Narda ELT-400 is the ideal measuring device when it comes to compliance with these standards. Benefits include the perfectly matched frequency range and implementation of the specified transfer function. The aim of this new generation Narda ELT-400 is to greatly simplify the assessment process. With the EXPOSURE STD (Shaped Time Domain) mode, the instrument achieves a new standard in simple but reliable measurement of magnetic fields, whether straightforward or in very complex field environments. Time-consuming and easily misinterpreted measurements with a spectrum analyzer or a scope are rendered obsolete. Detailed knowledge about the evaluation procedure or the field waveform or frequency is no longer needed. The results are reliable, and speed and ease of use are significantly improved over all traditional methods.
