Features
-
KCl impregnated glass bulb is permeable to hydrogen ions; reference filled with 3M KCl and has a porous Teflon junction. Salt bridge is formed between the two, and a potential is measured.
-
Choice of standard or integrated refillable reference
-
A special low ionic strength reference electrode is available for measuring waters with conductivities below 200 µS
-
Optionally paired with ORP sensor
