Glass-body conductivity cells are chemical-resistant. Epoxy/graphite, glass/platinum, stainless steel, and other sensors used with conductivity meters to measure a solutions ability to convey an electrical flow; available in two to four cell models; may include an ATC probe for temperature compensation. Designing small cells closer together can be necessary to measure extremely low conductivity, while the opposite is true for higher conductivity. Alternatively, an in-line conductivity probe that contains a range of very precise resistors that duplicate known conductivity measurements can be used. Four-pole electrodes are used in higher-conductivity applications which allow for frequent recalibration and diagnostics. If stirring is not possible due to limited sample volume or other reasons, it may be abandoned in both calibration and measurement. If the platinum black is dry, dirty, or peeled off, it will adversely affect the conductivity measurement.

When selecting a conductivity cell, check the expected conductivity of the sample and then look at the cell constants of conductivity cells. In general, the cell constant of the in-line conductivity electrode will not change; however, if the sensing elements are altered in some way (e.g. STs Series sensors are constructed from high-quality, durable materials that can be stored for long periods of time. For this reason, conductivity electrodes are frequently used to measure ionization or total dissolved solids (TDS) in water quality applications. 4-cell electrodes also have reduced maintenance because they can overcome the resistance caused by build-up of algae or debris. Four Electrode Conductivity Probes Principle. There are instruments that offer programmable temperature compensation, but that functionality comes with a price. Make sure to perform conditioning before use (See Conditioning). These conditions vary depending on the type of electrode, which is why we have different storage instructions for each sensor. If the conductivity cell has no built-in temperature sensor, check the solution temperature using a calibrated thermometer and enter that temperature into the meter. solid deposition or other fouling of the electrodes or insulator of the sensor, loss of electrode material through corrosion) the cell constant will change. Specifically for silver/silver chloride electrodes. Available on GSA/VA contract for Federal Government customers. Prior to calibration, select the desired measurement unit and enter the cell constant (indicated on the cap of the conductivity cell) into the meter settings.

Specific conductance, or conductivity, with regards to water quality is the measurement of how many and how mobile ions are in solution. The additional components to reduce polarization make the 4-cell electrode more expensive than the 2-cell but significantly improves accuracy under all conditions. However, it is recommended to verify the conductivity sensor or make calibration adjustment if necessary on an annual basis. Additional sensors are also installed in bodies of water surrounding agriculture to monitor the effects of runoff, thereby preventing algal blooms.
