説明
Definition of conductivity: Conductivity means the ability of a substance to transmit electric current, which is inverse to resistance. The unit of measurement 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 tester provides reliable measurement results with simple and fast operation. This pen-type conductivity meter is compact and easy to carry for handheld measurement. The LCD screen displays readings clearly.
