Desco ESD Work Surface Resistance Test Unit

This meter is perfect foreasily determining if asurface is dissipative,conductive, or insulative.Simply press and holdthe test button until thebright LEDs display thereading level. Unit featuresan automatic test voltageselector allowing the testvoltage to switch from 10Vto 100V if the measuredresistance exceeds 105ohms. Two banana jacks andan electrode toggle switchallow for the connection of two optional external 5-lb.electrodes that measure surface resistance point-to-point(RTT) or resistance to equipment ground (RTG) of largersurfaces (flooring, mats, etc.). Includes 9V battery and NIST-traceable Certificate of Calibration.
