Noncontact Eddy Current Sheet Resistance Meter with Multiple Sensors for Cross-Web Materials

  • Great for ensuring cross-web consistency
  • Works in vacuum or atmosphere, wet or dry processes
  • Dual bar configuration with user-defined number of sensor positions
  • Narrow and short profile allows for mounting in the most needed location
  • Noncontact measurement of ohms/square, ohms-cm, resistivity, thickness, and more
  • Choose sensors in one of four ranges, from .005 ohms/square to 100,000 ohms/square
  • Additional sensor positions can be added and existing sensors moved even after installation
  • Use Delcom software, Delcom web browser application, or integrate via Modbus with your own systems to monitor and record readings

Four Ranges to Choose From

Up to five significant digits available, depending on instrument range.

Options and upgrades

All options and upgrades are available for purchase with the original unit and for at least one year after purchase.

  • Vacuum-ready package:

    The sensor is vacuum ready; however, optional vacuum-ready cabling, brackets, and feedthrough(s) will be required for vacuum applications.

  • Optional computer:

    Delcom can source a laptop, desktop, tablet, or industrial touchpanel PC for customers, if needed.
