Which liquid conductivity standard should I use for calibration?A conductivity standard should be chosen that most closely matches the anticipated conductivity range of the process.
What can I use to clean the conductivity sensor electrodes if fouling occurs?The metal electrodes of 2 and 4-pole sensors can be cleaned with water and mild detergents and washed with deionized water after cleaning. Care should be taken to not use cleaning agents that can impact the material of the electrodes. Click to reference the knowledgebase article on cleaning for more information.
Does the cell constant of my conductivity sensor change over time?The cell constant of a conductivity sensor may change over time due to corrosion of the electrodes from an aggressive media, or due to fouling of the electrodes. Calibration adjusts the cell constant and can help offset these effects to a certain extent.
