Receivers: The Zonge ZEN Rx6 was the world's first ultra wide-band EM geophysics receiver system. It was co-developed by Zonge International, Inc. (Tucson, Arizona), and Oregon State University (Corvallis, Oregon) under a National Science Foundation Major Research Instrumentation award. Please see NGF Equipment Request Form under "NGF Request/Info" menu on the left to reserve ZEN Rx6 instruments for your survey or experiment.
The Zonge ZEN Rx6 (shown above with NGF manufactured electrodes is a flexible system that covers a wide frequency band with dc and micro-Hz to 4 KHz data acquisition with 32 bit precision at 256 Hz sample rates (approximately 130 dB signal-to-noise ratio on input). The data can be recorded continuously at full speed. The system has 10^9 ohms input impedance, and typically is configured to acquire 5 channels of sensors (electric field, magnetic field or others), although other configurations are possible.
Sensors: The NGF can equip Zonge ZEN Rx6 receivers with Zonge ANT/4 induction coils covering the range of 0.00001 Hz to 650 Hz.
We can provide stable and environmentally benign OSU dual chamber Pb-PbCl2 gel-type electrodes or Borin solid state Ag-AgCl electrodes to use in measuring electric field variations.
Field computers can be supplied, if available, equipped with our Python-based instrument graphical user interface (GUI) to set up and operate the Zonge ZEN Rx6 and the Narod NIMS receiver systems, or the software can be loaded on to your field computers.
