  • Page 15 Two selectable temparature sources are available: reading directly from the sensor inside the probe or manual entry. Three options of compensating temperature are available: Linear Temperature Compensation: The conductivity of a solution with a specific electrolyte concentration changes with temperature. The relationship of the change in conductivity as a function of temperature is described by a solution’s temperature coefficient.
  • Page 16 The conductivity of an aqueous solution is the measure of its ability to carry an electrical current by means of ionic motion. The conductivity invariably increases as the temperature rises. It is affected by the type and number of ions in the solution and by the viscosity of the solution itself. Both parameters are temperature dependent.
