Process Electrodes From Eutech Instruments


Process,Electrodes,pH,ORP,Conductivity,Eutech,InstrumentspH measurement is usually done with the use of a combination electrode. The combination electrode is an electrode system formed by a glass sensing half-cell and an internal reference half-cell. As the reference junction acts as the medium of conductor between the reference electrolyte and the sample to be measured, it must allow free movement of electrons through the junction and into the sample.

A potential develops on the membrane surface when a pH electrode comes into contact with a sample and its value varies with the pH of the sample. This variation in potential is measured in mV by a meter and is converted to direct pH values.

The selection of a suitable electrode depends on the types of application.

Model: ECFP21A1A1 pH Differential Electrode
Model: ECFR21A1A1 ORP Differential Electrode

Process,Electrodes,pH,ORP,Conductivity,Eutech,Instruments

Unlike conventional combination electrodes, the differential electrode is designed for more durability in harsh industrial environments such as wastewater treatment. The unique electrode design prevents fouling of the reference electrode system. The salt bridge and reference solution is replaceable hence providing greater reliability, better accuracy and a more cost effective measurement system.

Product Features:

  • Extended electrode life - Larger reference chamber filled with buffer solution minimises the effects of dilution and prolongs electrode life.

  • Cost savings - The soiled salt bridge and buffer reference solution can be easily replaced at a fraction of the cost of a new combination electrode.

  • Cost savings - The soiled salt bridge and buffer reference solution can be easily replaced at a fraction of the cost of a new combination electrode.

  • Automatic Temperature Compensation - Built-in temperature sensor.

  • Up to 3000 feet signal transmission - Built-in preamp eliminates high impedance wiring problems hence signal transmission is possible up to 3000 feet and hand capacitance is prevented.

  • Minimized susceptibility to ground loops - With differential pH/ORP measurement technology.

  • Optimal mounting positions - Compact design ensures less obstruction when used in pipe mountings and universal 1.5" NPT mounting threads enables optimal mounting positions.
