Jul 15, 2008 Designed for broadband measurement of electromagnetic energy, hand-held Model NBM-520 works with calibrated probes covering frequencies from 100 kHz to 60 GHz. Probe types include electric and magnetic field, flat or shaped response, and diode and thermocouple detectors. With supplied software, user can pre-configure meter for specific survey task and manage data required for survey reports. Meter can be employed by safety personnel to evaluate compliance of facilities with IEEE standards.

Jan 14, 2002 Model EFA-200 and EFA-300 analyze low-frequency magnetic and electrical fields to determine safety or potential for harm from high-voltage utility lines and industrial equipment such as resistance welders. Analyzers use Shaped Time Domain (STD) technology to measure in low frequency range of 5 Hz to 32 kHz. They calculate and display field strength levels as percent of industry or government standard, irrespective of signal frequency and waveform.
