Conductivity Setup Menu Features

Temperature Compensation and Reference Temperature
The Orion Star and Star Plus conductivity meters have the ability to use a
temperature compensation feature that calculates and displays the conductivity
measurements at a reference temperature of 5 °C, 10 °C, 15 °C, 20 °C or 25 °C
(Orion Star meters have a reference temperature of 15 °C, 20 °C or 25 °C only) .
The temperature compensation can be set as linear for most aqueous samples,
non-linear for ultra pure and low ionic strength samples or off for non-temperature
compensated conductivity measurements .
The closer the sample temperature is to the selected reference temperature, the
more accurate the conductivity measurement will be, especially if the temperature
compensation coefficient is estimated or inaccurate .
