4-Pole sensors were designed for the measurement of liquid conductivity. The engineering design based on 4-electrode principle guarantees excellent linearity from 1 μS/cm up to 300 mS/cm. The main application for Conducell sensors is the in-line measurement under demanding conditions found in biotechnology and pharmaceutical applications.

Can Hamilton conductivity sensors be used with my existing transmitter?
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.
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.
