Desco SPP2 - Static Charge Meters, Pen Probe Two-Point, Volume Resistant, Spring Loaded Electrodes
The Desco SPP2 is a two-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 these probes convenient for auditing small samples of materials in the field, and yet their design specifications make these instruments precise enough for laboratory environments.
This 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.
Direct point-to-point resistance measurements with the Two-Point Pen Probe, SPP2, generally conform to the guidelines as outlined in the ANSI/ESDA 11.13 two-point resistance measurements. The two-point pen probe uses a thin line BNC coaxial cable with inner source and outer sense connections to minimize reading errors due to electrostatic interference. The BNC to banana jack adapter allows connection to the most popular meters in the market.
