Conductivity Analyzers

What is Conductivity?

Conductivity is the measure of a solution's ability to pass or carry an electric current. The term Conductivity is derived from Ohm's Law, E=I•R; where Voltage (E) is the product of Current (I) and Resistance (R); Resistance is determined by Voltage/Current. When a voltage is connected across a conductor, a current will flow, which is dependent on the resistance of the conductor.  Conductivity is simply defined as the reciprocal of the Resistance of a solution between two electrodes.

How do we measure Conductivity?

There are two basic sensor styles used for measuring Conductivity: Contacting and Inductive (Toroidal, Electrodeless).

When Contacting Sensors are used, the conductivity is measured by applying an alternating electrical current to the sensor electrodes (that together make up the cell constant) immersed in a solution and measuring the resulting voltage. The solution acts as the electrical conductor between the sensor electrodes.

4-Wire Conductivity Analyzer

The model FLEXA® two-wire analyzer is used for continuous on-line measurements in industrial installations. It offers an option for single or dual sensor measurement, making it the most flexible 2-wire analyzer available. The model FLEXA® modular designed series analyzer offers 4 parameter choices – pH/ORP (oxidation-reduction potential), contacting conductivity (SC), inductive conductivity (ISC) or dissolved oxygen (DO) – with the respective sensor module.

Dual-Channel Conductivity Analyzer

Designed to accept two sensor inputs. Differential, ratio, deviation, % passage or % rejection can be indicated and/or transmitted.

Hazardous Area Conductivity Transmitter/Analyzer

Intended for the conductivity/resitivity applications in Class I Div I and Class I Div II areas.

Universal Contacting Conductivity Analyzers

The Contacting Conductivity method is especially suitable for low and ultra pure conductivity measurements. The analyzer works with a contacting conductivity sensor with built in temperature element.

Inductive (Torodial, Electrodeless) Conductivity Analyzer

The Inductive Conductivity method is especially suitable for high conductivity measurements. The analyzer works with a sensor with two toroidal transformers built in. An AC current induces a voltage in the process sample that results in a current in the sample. The strength of this current is proportional to the conductivity of the sample following Ohm's law.
