Liquid analysis sensor / transmitter : pH, conductivity, ORP dissolved oxygen
XEROLYT®
Mettler Toledo, Process Analytics AG
METTLER TOLEDO pH/Redox electrodes with gel- or liquid-type electrolyte or solid polymer (XEROLYT®) reference system, all with open junction, obviate the need to pressurize the electrode through the housing. The gel electrode is pre-pressurized and the polymer reference system is (process) pressure-resistant. These types of electrode cannot be refilled and therefore require reduced maintenance.
They are widely used for routine measurements, particularly in applications involving media with a high fouling potential. Many models enable temperature-compensated measurements and enhanced sensor diagnostics.
Some pH-electrodes with integrated ISM functionality (Intelligent Sensor Management) allow "Plug and Measure" and advanced diagnostics.
