1.Surface resistance tester uses ASTM standard D-257 parallel electrode sensing method to easily and repeatedly measure various conductive, electrostatic discharge and insulated surfaces.
2.There is a copper strip test wire on the back. When measuring, the copper wire is close to the object to be measured, and it can be measured, which is convenient and safe. In case of small items, you can use the standard alligator clips to measure.
Measuring surface resistance: Place the tester on the surface to be tested, press and hold the red TEST button, and the continuously lit light-emitting diode (LED) indicates the magnitude of the measured surface impedance.
