CRL R-Chek Surface Resistivity *DISCONTINUED* Polyurethane Sealants or to surfaces that areFour Point Sheet Resistance Meter The resistance of a thin film coating is directly proportional to the resistivity and is an important Quality Control component of a coating. Therefore, resistivity may be the largest single item to determine the repeatability and function of a coating. Sheet resistance has the units of ohms, but it is convenient to refer to it in ohms per square since the sheet resistance produces the resistance of the coating within
