    Instruction Manual PCD 650 7. APPENDIX 7.1 Conductivity theory Conductance is a quantity associated with the ability of primarily aqueous solutions to carry an electrical current, I, between two metallic electrodes when a voltage E is connected to them. Though water itself is a rather poor conductor of electricity, the presence of ions in the water increases its conductance considerably, the current being carried by the migration of the dissolved ions.
  • Page 113 Instruction Manual PCD 650 The PCD 650 series meter not only measures conductivity readings from micro or milli Siemens but also reads resistivity (Ohms, kOhms and MOhms), TDS (ppm and ppt), and salinity (ppt). The salinity scale which ranges from 0 to 80 ppt is a measure of all salts, not just sodium chloride.
