HI-3604 ELF Survey Meter

Precision Low-Frequency Electric and Magnetic Field Meter

The HI-3604 ELF Survey Meter delivers precise, True RMS measurement of low-frequency electric and magnetic fields from 30 to 2000 Hz, making it an indispensable tool for power-frequency investigations, safety assessments, and environmental studies. Its custom LCD display provides clear field readings in volts/meter, gauss, tesla, or amperes/meter, while a built-in bar-graph assists users in quickly identifying field peaks and locating hot spots. The unit’s full auto-ranging capability ensures accuracy across a wide dynamic range, and its sealed membrane control panel enables reliable operation in demanding field environments. With onboard memory capable of logging up to 112 readings, users can efficiently document surveys for later analysis and reporting. Compact, lightweight, and built with rugged construction, the HI-3604 supports long-duration fieldwork without sacrificing measurement stability. Whether deployed by engineers, industrial hygienists, or health and safety professionals, this instrument delivers the clarity, reliability, and performance required for critical decision-making in power-frequency field evaluations.
