Features:
●Surface Resistance Tester/S.R Meter is an ultra wide-range.Battery operated and portable instrument for measuring surface Resistivity of Virtually and flat surface conforming to ASTM D-257 standard by using recommended parallel bar sensing probe.
●The surface resistivity is conveniently indicated by a row of LEDs covering a total of 10 decades from 10E3 to 10E12 ohms per square.
