Technical Specs



Measure Resistance of ESD Packaging

Designed originally for flat (planar) packaging materials, the portable PRF-911 Concentric Ring test fixture will measure Surface and Volume Resistance of virtually any flat material in accordance with current ESD Association Standards.It will measure Surface Resistance per ANSI/ESD STM11.11, and Volume Resistance per ANSI/ESD STM11.12, and will approximate surface and volume resistivity measurements per ASTM D-257.

Note that ANSI/ESD Standards are for materials employed for electrostatic discharge control, while ASTM D-257 is used to assess insulating materials utilized in electrical distribution and power applications.


Complete Packaging Test Kit

The PRF-911 Concentric Ring is to be attached to the PRS-801 Resistance System included in this Packaging Test Kit.This system will can also give you Surface Resistavity by multiplying the surface resistance measurement in ohms by 10 to obtain surface resistivity in ohms/square.


Measure Anti-Static Bags
The small profile of the PRF-911 Concentric Ring allows the fixture to be inserted into small flexible containers, such as an Static Shielding, Anti-Static Bags or Moisture Barrier Bags, without having to cut the package.
Maintains Consistent Contact

The PRF-911 incorporates a spring loaded, self-aligning center electrode feature. This unusual feature aids in maintaining consistent contact of the fixture’s highly conductive rubber electrode surfaces with materials under test.

This reduces the need for frequent calibration and alignment of the fixture.

A Dual Test Bed for the either Measurement

The PTB-920 Dual Test Bed that’s included in this kit consists of an insulated test surface for ANSI/ESD STM11.11 Surface Resistance Measurements laminated to a steel test plate, which is employed for Volume Resistivity measurements.The four inch diameter steel test bed assembly includes a banana receptacle for instrument connections during volume measurements.

Portable, Wide Range System
This ESD Packing Test Kit will accurately meausure resistance from less than 100 ohms (<1.0x102 ohms), to greater than 1.0×1012 Ohms (>1.0×1013 ohms/square). The PRF-911 is designed so that it can be connected to either the ground reference of the PRS-801 or earth ground to minimize the effects of extraneous fields and charges on the measurement.
