The ELT-400 is an innovative exposure level meter for measuring magnetic fields in the workplace and in public spaces. The model is designed for health and safety professionals in industry, the insurance business and service industries. The instrument can simply and precisely handle practically any level measurement required in the low and medium-frequency range. It is comparable to the sound level meters that are commonly used in the assessment of noise at the workplace. Production Areas The ELT-400 is useful for checking fields caused by various manufacturing plant, including induction heating,...

waveform or frequency is no longer needed. The results are reliable, and speed and ease of use are significantly better than all traditional methods. > The ELT-400 covers the wide frequency range of 1 Hz to 400 kHz. The measurement range of the ELT-400 is far wider than the reference limits of common guidelines. The instrument has an external isotropic magnetic field probe with a 100 cm > 2 cross-sectional area. This is suitable for standards-compliant measurement even in non- homogeneous fields. The ELT-400 has a rugged housing and is easy to operate using only six buttons. The measurement result...

(valid for all imaginable waveforms) are directly handled by EXPOSURE STD mode. This completely eliminates the need to analyze the waveform in the time domain using a scope. Even when faced with pulses that include DC fields, the EXPOSURE STD method provides valuable results. The ELT-400 covers all the signal components down to 1 Hz that are relevant in assessing such a situation. Occasionally both the RMS value and the peak value are critical for assessing exposure in the low-frequency range. Both detector types are provided, and are simultaneously activated in the default setting. Depending...

Three-Axis Analogue Signal Output For scientific studies or advanced signal-shape / frequency analysis, a scope or an FFT analyzer can be connected to the analogue output. The output signal ensures proper phase within the three axes and covers the full bandwidth of the instrument. The buffered output provides an adequate voltage swing to allow for simple operation.
