Complete Packaging Test Kit
The PRF-911 Concentric Ring is to be attached to the PRS-801B Resistance System included in this Packaging Test Kit. This system will also give you surface resistivity by multiplying the surface resistance measurement in ohms by 10 to obtain surface resistivity in ohms/square. The PRF-911PT meets requirements from ANSI/ESD STM11.11, ANSI/ESD STM11.12 snd IEC 61340-2-3. It will also approximate surface and volume resistivity measurements per ASTM D-257.

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 per ANSI/ESD STM11.12. 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 1.0x10¹² Ohms (>1.0x10¹³ ohms/square). The PRF-911 is designed so that it can be connected to either the ground reference of the PRS-801B or earth ground to minimize the effects of extraneous fields and charges on the measurement.
