Conductivity Electrodes Product Description
In research and development, manufacturing, and quality control, SI Analytics ScienceLine conductivity electrodes have long since become standard for the most demanding measuring tasks.  Each conductivity electrode has an individual serial number making documentation easier and more traceable.  The ScienceLine conductivity electrodes from SI Analytics not only have high measurement accuracy, stability, and long service life, but are highly adaptable to your measuring requirements.

Conductivity electrodes measure the composite ion concentration of a solution.  Conductivity electrode measurement applications range from monitoring process water in industrial plants to measuring ultrapure water in quality control labs.  Consequently, a wide range of conductivity electrodes have been designed to meet these different applications.  The flow-through conductivity electrodes, LF 213T and LF 313T, with a cell constant of 0.1 and 0.01 cm-1 are ideal for the measurement and control of pure water.  With an extremely wide measuring range, an abrasion proof graphite housing, and an automatic resistance compensation feature, the LF 413T combined 4-pole conductivity electrode is ideal for most applications, has a long life while providing you with accurate measurements even with a dirty conductivity cell.  The glass platinum conductivity electrode LF 713T (4-pole) and LF 913T (5-pole) allow the determination of conductivity in organic media.  The models LF 1100(T)+, LF 4100+ and LF 5100(T)+ offer the possibility of connecting these conductivity electrodes to diverse instrument types via the SMEK plug head and appropriate cable.

Conductivity electrode measurements
Conductivity is a parameter used to measure the ionic concentration and activity of a solution.  The more salt, acid or alkali in a solution, the greater its conductivity.  The unit of conductivity is S/m, often also S/cm.  The scale for aqueous solutions begins with pure water at a conductivity of 0.05 uS/cm (77 °F /25 °C).  Naturally occurring waters such as drinking water or surface water have a conductivity in the range 100 - 1000 uS/cm.  At the upper end of the chart some acids and alkalines can be found.

Conductivity electrode measurements are used for a wide range of applications such as the production of ultrapure water or determining the salinity of sea water.

Conductivity is measured by using a conductivity electrode to make a measurement of the electrical resistance.  The simplest kind of conductivity electrode used consists of two similar poles.  An alternating voltage applied to one of the conductivity electrode's poles causes the ions in the solution to migrate towards the pole.  The more ions in the solution, the greater the current which flows between the conductivity electrode's poles.  The conductivity meter measures the current produced by the conductivity electrode and uses Ohm's law to calculate first the conductance of the solution and then - by taking the pole's cell constant into account - the conductivity.
