• High chemical resistance

• Pressure limit: up to 20 bar

• Long lifetime

• Without liquid bridge

• No KCl leaking

APPLICATIONS

• Ultrapure water

• WWTP

• Polluted fluids (acids such as H2S, NH3, etc.)

• Dirty fluids (convenient if coatings remain humid and conductive)

• Fluids with sulfides (eg, sulfur recovery plants)

• Measurements in fluids with suspended solids and emulsions

DESCRIPTION

Standard electrodes are generally provided with a porous junction which allows the reference system to come into contact with the monitored solution. When high pressure or temperature occur, or with highly basic or acid solutions, the monitored fluid may penetrates in the reference system. In this case, the electrode is quickly contaminated and out of use.

The 2000 series electrodes have an Ag / AgCl reference cell incorporated in an ion-conductive polymer, the outer surface of which forms a static electrolyte and the contact bridge. These electrodes are not using a ceramic or any kind of diaphragm. So, the reference system is protected from pollution and poisoning by pollutants.

Compared to conventional electrodes, the 2000 series electrodes therefore have a much wider range of applications and a much longer lifetime.
