Concentric-Point Pen Probe

Pen Probes work with most megohm meters, electrometers and other high potential resistance meters in most Resistance Kits for measuring Surface Resistance and Volume Resistance of materials with physical dimensions too small for regular concentric ring or other probes. The size, portability and construction make these probes convenient for auditing small samples of materials in the field and yet their design specifications make these instruments precision enough for laboratory environments.

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.
