Witryna20 sty 2024 · Temperature exerts a significant positive influence on electrical conductivity. Most commercial conductivity meters simultaneously measure temperature and conductivity, and typically apply a correction factor of 2% °C −1 to give electrical conductivity at standard temperatures of 20° or 25°C. This implies that … WitrynaTemperature causes an increase in conductivity. Between 1.5 and 5.0% per °C, this rise is substantial. Therefore, unless a temperature correction is applied, the conductivity of the same solution measured at different temperatures will vary. Because of this, conductivity data need to be temperature adjusted.
