Non-Contact Eddy Current Resisitivity Meter with Multiple Sensors for Measuring Sheet Resistance Cross-Web

  • Non-contact measurement of Ohms/sq, Ohms-cm, resistivity, thickness, and more
  • Great for ensuring cross-web consistency
  • Works in vacuum or atmosphere, wet or dry processes
  • Choose a sensor in one of four ranges, from .005 Ohms/sq to 100,000 Ohms/sq—add other sensors later
  • Dual bar configuraion with user-defined number of sensor positions
  • Use Delcom software, Delcom browers application, or integrate via Modbus with your own systems to monitor and record readings

Four Ranges to Choose From

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, for vacuum applications optional vacuum-ready cabling, brackets, and feedthrough(s) will be required.

  • Optional computer:

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