Static Charge Meters, Pen Probe Single-Point, Volume Resistant, Spring Loaded Electrodes
The Desco SPP1 is a single-point pen probe that works 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 rings or other probes. The size, portability, and construction make this probe convenient for auditing small samples of materials in the field, and yet their design specifications make these instruments precise enough for laboratory environments.
This pen probe uses 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 a minimum of 60 micro-inch hard gold. The single-point pen probe can be used for measuring the volume resistance of small planar material samples per the requirements of ANSI/ESDA 11.12 or measuring resistance to the ground of materials or components on a piece of equipment.
