Model 800 Series Spring-Loaded Resistance Probes
The Series 840 Resistance/Resistivity Probes enable the user to measure the surface resistance of flat, uneven or curved objects using spring-loaded electrodes. The Series 840 Resistance/Resistivity Probes, all utilize gold-plated, spring-loaded, flat tip pins as the contact electrode. Each pin requires 5-oz (688 gm.) of force for total compression. The electrodes are socket-mounted allowing for easy replacement by the user. The SOURCE/SENSE electrodes are separated by a Teflon® core for high insulation resistance and when compressed, extend 0.5” (13 mm) beyond the core.
All Probes, except the Model 823, have standard BNC output jacks and can be connected directly to any 2-wire resistance meter using the appropriate cable (3-ft BNC to separate banana plug cable standard for stand-alone Probe test heads). The Model 848 Handle Assembly has a fixed, 3’ (92cm) 3-wire, Teflon shielded cable with standard banana plug terminations for Source,Sense and Ground. It fits the Model 841, 842, and 844 Probes, and provides both user convenience and reduced cost associated with having a single cable assembly.
