Resistance of Powder and Granulated Materials
The PRF-930 Powder Resistance Fixture measures the bulk resistance of powder and granulated materials. Test material is placed in the cavity between the measurement plates. Once a measurement has been made in ohms, a fixture calculation, or correction factor, converts the resistance measurement to volume resistivity in ohm-cm.
Superior Accuracy

The PRF-930 provides the most accurate measurements when used with a precision wide range resistance instrument, such as the PRS-801 Resistance System, or equivalent laboratory system. For guarded plate measurements use an instrument ground reference.
