Definition of conductivity: Conductivity refers to the ability of a substance to transmit electric current, which is reciprocal to resistance. Its measuring unit is Siemens/cm (S/cm). 10⁻⁶ of this unit is expressed as μS/cm, and 10⁻³ is expressed as mS/cm. The 138 series pen-type tester delivers reliable readings with simple and fast operation. This pen conductivity meter is compact and portable for handheld measurement, with LCD screen for measurement readout.
