US imports ACL380 surface resistance tester
ACL-380 uses ASTM standard D-257 parallel electrode sensing method to easily and repeatedly measure various conductive, electrostatic discharge, and insulated surfaces.
use:
To measure the surface impedance, place the watch 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.
