Evaluate the Uniformity of Films Coated on Plate Glass

The surface resistance of films coated on plate glass can be measured using a double ring electrode.


Just put the double ring electrode on the measurement object and the surface resistance can be measured. Up to now, a measurement sample in the specified size must be cut out of the glass of a mobile device or smart phone to measure the surface resistance, but the SM9001 Surface/Volume Resistance Measurement Electrode and the SM-8220 Super Megohm Meter enable performing measurement without the need to cut out the measurement sample, so the uniformity of the surface coated film can be evaluated easily.
