Resistivity Testing Service
Resistivity Testing Service for Conductive and Non-Conductive Materials. OAI Resistivity Test Lab; Answering the growing demand for resistivity testing, OAI is now offering conductive and non-conductive materials testing in their Resistivity Test Lab in San Jose, CA. Tests are completed within ten days of receipt of test sample material, and each test results in a comprehensive report. Resistance is measured in ohms; resistivity is measured in ohms/square (surface resistivity) and ohms•cm (volume resistivity).
About resistivity measurement
A material`s resistance is simply defined as its inherent resistance to current flow in ohms. Surface resistivity (or sometimes called sheet resistance) describes the resistance within an area of the sample. To distinguish surface resistivity from resistance, surface resistivity is usually expressed in units of Ω/square.
