4 Point Surface Resistivity Meter - RC2175

"R-Chek"
Four Point Sheet Resistance Meter

Remove all doubt and be sure that your product is coated properly... Without breaking the bank!

EDTM, Inc. is proud to offer four
point sheet resistance meters for under $500 that are calibrated to standards that are traceable to a NIST traceable source.

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 any square area. This parameter is therefore measured using the 4-point technique.
