What is temperature compensation for conductivity?
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.
How do you calculate temperature compensation?
This temperature compensation is calculated by applying an industry standard 2% to the conductivity value for every degree away from 25°C the temperature reads.
How does conductivity change with temperature?
When temperature increases, the vibration of metal ions increases. This results in increase in resistance of metal and hence, decrease in conductivity. In electrolytic conductors, the ions are charge carriers and with increase in temperature, ionization increases and hence, conductivity increases.
What is automatic temperature compensation on conductivity meter?
Why is it important? A: ATC stands for Automatic Temperature Compensation. This means the meter measures pH and temperature at the same time, then automatically calculates to correct for differences (e.g. if one sample is 20°C and another is 23°C).
