Conductivity Sensors

The measurement of specific conductivity in aqueous solutions is becoming increasingly important for the determination of impurities in water or the concentration measurement of dissolved chemicals.

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.

Contacting Conductivity Sensors SC42/SC4A

The measurement of specific conductivity in aqueous solutions is becoming increasingly important for the determination of impurities in water.  Yokogawa has designed a full range of precision sensors and instruments to cope with these measurements, even under extreme conditions.

Pure Water (low) Conductivity Sensors SC4A/SC42

Intended for the low conductivity applications found in the semi-conductor, power, water and pharmaceutical industries, these sensors are in a convenient compact style.

Biotech/Pharma Contacting Conductivity Sensors

The Hamilton CONDUCELL 4US sensors for Triclover and INGOLD process connections has often been successfully used where the access port is too narrow for the Inductive Sensors.

High Pressure/High Temperature Conductivity Sensor SC42/SX42

These conductivity cells have extremely high temperature and pressure ratings: the threaded types can handle 16 bar at 200°C and the flanged types can handle 40 bar at 250°C.

Inductive (Torodial, Electrodeless) Conductivity Sensor ISC40

The model ISC40 sensors are designed for use with the EXA ISC analyzers. This combination exceeds all expectations for conductivity measurement in terms of reliability, accuracy, rangeability and price performance. 

Percent Concentration Sensors ISC40

There are numerous industrial applications where measurements and/or control of a specific chemical strength of the process is critical for optimizing the production of the end product. These specific concentrations are obtained by mixing a full strength solution with water to achieve the desired percent concentration.  

High Conductivity Sensors ISC40/SC42

Portable Conductivity Handheld Meter SC72

Compact, lightweight, and dripproof, the SC72 is the ideal Conductivity meter for field use. Features wide-range auto-ranging, automatic temperature compensation, self-diagnostic functions, and a large, easy-to-read LCD display.

PC Flow Block

Many botech and pharmaceutical applications for determining the purity and quality of the finished product, require the measurement of pH and conductivity in very low volume samples. The PC Flow Block assemblies were specifically designed to achieve accurate pH and conductivity measurements in such low volume applications.
