SPP1, SPP2 and SPP3 Pen Probes use spring loaded electrodes with conductive rubber boots to ensure intimate contact with hard/irregular surfaces and reduce contact resistance. All electrodes are field-replaceable, spring-loaded, pogo-pin type ATE-quality probes that are made of beryllium copper with minimum 60 micro-inch hard gold.
The Single-Point Pen Probe can be used for measuring volume resistance of small planar material sample per the requirements of ANSI/ESDA 11.12 or measuring resistance to ground of materials or component on a piece of equipment.
Direct point-to-point resistance measurements with STATICO Two-Point Pen Probe, SPP2, generally conform to the guidelines as outlined in the ANSI/ESDA 11.13 Two-Point Resistance Measurements.
