The Conducell 2DC-PG 2-Pole sensor is a basic low-cost sensor ideal for contaminant free processes. It's 1.0 cell constant allows for measurements from 0 to 20 mS/cm. The plastic shaft and graphite electrode are easy to clean. The 5 M fixed cable allows for easy submersion beneath the liquid surface. This product must be connected to a conductivity transmitter such as the H100.
Technical Drawing - Conducell 2DC-PG Conductivity Sensor
Which liquid conductivity standard should I use for calibration?
Does temperature affect conductivity measurement?Yes, temperature has a direct impact on conductivity. Increasing temperature increases the mobility of ions within a solution and results in higher conductivity measurements. Temperature compensation can be performed using empirically derived temperature coefficients, which may be different for various solutions.
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.
