Laajamittaiset johtokykykennomme käsittävät kolmea mittaustekniikkaa: 2-elektrodiset kennot µS/cm alalle, 4- ja 6- elektrodiset sensorit mS/cm alalle sekä elektrodittomat sensorit (toroidi).
Moni-elektrodiset ja elektrodittomat sensorit ovat käytössä laitteissa jotka ovat kosketuksissa voimakkaiden kemikaalien kanssa tai missä sensorit voivat likaantua.
Täydelliset asennusmenetelmät ovat suunniteltu sopimaan lähes jokaiseen prosessiosa-alueelle: lisäys, läpivirtaus, upotus sekä sisäänotto.

2-Electrode Contacting Cells - Range 0 ... 10,000 µS/cm
Tarkka tekniikka joka soveltuu johtokyvyn tarkkailuun puhtaassa vedessä tai teollisessa huuhteluvedessä. Vuoroittainen virta kulkee kahden elektrodin välissä ja lähetin muuttaa potentiaalieron johtokyvyksi, pitoisuudeksi tai tietyksi vastukseksi.
