The conductivity is a cumulative para-meter for the ionic concentration of asolution. The more salt, acid or alkali ina solution, the greater its conductivity.The unit of conductivity is S/cm. Thescale for aqueous solutions begins withpure water at a conductivity of0.05 µS/cm (25°C). Naturally occurringwaters such as drinking water or surfacewater have a conductivity in the range100 - 1000 µS/cm. The upper end of thescale is reached by some bases such aspotassium hydroxide solutions with aconductivity of just over 1000 mS/cm.

In practice conductivity measurementsare used for applications such as moni-toring plants in which ultrapure water isproduced and determining the salinity ofsea water.

Conductivity is measured by making ameasurement of the electrical resistance. The simplest kind of measuring cell usedconsists of two similar electrodes. An alternating voltage applied to one of theelectrodes causes the ions in the solution to migrate towards the electrodes. Themore ions in the solution, the greater the current which flows between theelectrodes. The instrument measures the current and uses Ohm's law to calculatefirst the conductance of the solution and then - by taken the cell data into account- the conductivity.

TetraCon® conductivity cells

For more than 50 years WTW has been one of the leading manufacturers worldwideof precision conductivity meters and cells.

The TetraCon® 4-electrode system is the perfect result of a logical, practice-orientedfurther development and sets a new standard for professional conductivitymeasurements.

In comparison with conventional measuring cells with 2 electrodes, the TetraCon®

conductivity cell offers numerous technical advantages:

• Highest degree of precision and linearity by optimized cell geometry

• Extremely large measuring range with just one cell

• Long-term cell constant stability with high-quality abrasion-resistant graphiteelectrodes

• With built-in temperature sensor as standard

• Smallest immersion depth possible

• Ideal sample exchange – no dead volume

• No measuring errors even with very dirty electrode – contact resistance on theelectrode surface is automatically compensated

• No measuring errors from cable influences

• No measuring errors from primary or secondary polarization effects

• No measuring errors from alteration to the electrical marginal field during contactwith base or side walls

• No danger of breakage owing to robust epoxy casting technique
