Superior data-logging performance begins with MCM's tried and tested digital voltmeter.

  • Selectable input impedances (10, 75, 400 MΩ)
  • Selectable full-scale ranges (AC and DC ranges)
  • AC rejection on DC ranges
  • High voltage isolation - up to 1kV steady-state and 15kV transient (momentary) overload protection
  • MCM's advanced survey application programs are pre-installed on the data-logger and ready for action.
  • 512 MB of non-volatile CompactFlash memory available to store your survey data (replaceable memory)
  • Built-in WAAS-enabled GPS receiver available for automatic logging of critical position fixes. (also unit is external GPS receiver ready)
  • Survives 6 foot drop to concrete (die-cast magnesium alloy construction)
  • IP 67 rating (dust/water intrusion)
  • -20°C to 60°C operating temperature range.

Pipeline Survey Options with the G1:

  • Trigger-mode CIS (both manual & automatic triggering)
  • Timer-mode CIS
  • DCVG surveys
  • Combined DCVG/CIS surveys(single-pass)
  • Time-based data-collecting in stationary mode (GPS time stamping for accurate data compensation when telluric and/or stray currents are picked-up / discharged randomly during a CIS)

Survey screen shows a graphical representation of the data as they're being recorded, including registered survey flags (F) and test stations (D), for convenient real-time monitoring of collected survey data.

corrosion monitoring Graphical reports, including pipeline overlaid on topographical map, can readily be produced by uploading the data collected on the G1 to ProActive, our advanced, easy to use, software program.

Site Survey (Annual & Bi-monthly) Data Collection with the G1:

  • Routes are created using MCM's software program, ProActive, and route data are easily downloaded to the G1 data-logger.
  • Voltmeter settings for each reading prompt are selected in ProActive and are conveniently displayed on each prompt screen.
  • Voltmeter readings are displayed on each reading prompt screen when the G1 is connected to a device.
  • Prior Readings data are downloaded with the route data and are displayed on each reading prompt screen for convenient reference.
  • Data from completed site surveys are easily uploaded to ProActive for integration with historical CP data.
