For example, the conductivity measured in a 0.01 M KCl solution at 20°C is 1.273 mS/ cm, whereas at 25°C, it is 1.409 mS/cm. The concept of reference temperature (normalization temperature) was introduced to allow the comparison of conductivity results obtained at...
  • Page 48 is the value taken at the measurement temperature. The Large Display Salinity (Model 850036) and Conductivity (Model 850037) Pens automatically use linear temperature correction. Linear Temperature Correction In moderately and highly conductive solutions, temperature correction can be based on a linear equation involving a temperature coefficient (θ).
  • Page 49 Note… The correction is accurate only within a limited temperature range around T1 and T2. The greater the difference between T and Tref, the higher the risk of error. Calculating Temperature Coefficients (θ) By measuring the conductivity of a sample at temperature T1 close to Tref and another temperature T2, you can calculate the temperature coefficient by APPENDICES...
