"R-Chek +" Four Point Sheet Resistance Meter


Remove all doubt and be sure that your product is properly coated... without breaking the bank!  EDTM is proud to offer budget-friendly Four Point Sheet Resistance Meters 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 most important factor in determining the repeatability and function of a coating. Sheet resistance has the unit 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. Therefore, this parameter is measured using the 4-point technique.


Pocket Size Protection for Production, R & D, Sales, and Quality Assurance personnel who must know their products are coated properly.
