Four Point Probe for measuring electrical conductivity

This solicitation from the National Aeronautics and Space Administration Shared Services Center seeks quotes for a four-point probe system to measure electrical conductivity. The system must accommodate samples up to 10 inches by 10 inches, with a probe head capable of positioning tungsten carbide probe tips between 0.005 inches and 6 inches from the sample surface. Quotes will be evaluated based on meeting the technical requirements outlined in the statement of work and having the lowest price. Quotes are due by 1:00pm Central Time on November 22, 2023.

The opportunity is set aside for total small business and will be awarded to the responsible offeror submitting a technically acceptable quote with the lowest price. The NAICS code is 334516 and PSC code is J070. Performance will take place in Huntsville, Alabama. The four-point probe system must measure sheet resistance from 1 milliohm-per-square to 100 Megaohms-per-square and volume resistivity from 10E-3 to 10E6 ohms-cm, with an accuracy of within 0.3%.
