What is T/C and reference temperature and how do they affect conductivity?
T/C stands for Temperature Coefficient and is a sample-specific factor that can be adjusted in the conductivity meter to direct the reading. T/C is used to compensate back to a particular reference temperature. Reference temperatures are typically 20 or 25 degrees Celsius. Orion conductivity meters can have a wide range of Temperature Coefficients including percent (%), nLF (non linear function algorithms),uNLF (ultrapure water non linear function algorithm and no compensation (zero). When a nonzero T/C is entered in the setup menu of your meter, the display will automatically read the conductivity at the set reference temperature of 20 or 25 degrees Celsius, depending on the meter model. If the temperature coefficient is set to zero, the conductivity reading will be displayed uncompensated, ie. The meter will display the actual conductivity reading at the existing sample temperature. Depending on the specific Orion conductivity meter that you have, the temperature compensation capabil
