Electrode Support

Our Electrode Support is a great complement to the Vernier Stir Station, as well as a perfect holder for many sensors. It is built to connect to all standard ring-stand posts; its large-handled locking nut keeps your sensors firmly in place. The larger opening (13 mm in diameter) is perfect for our pH, ISE, Conductivity and ORP sensors. The smaller opening (5 mm) is designed to hold our Stainless Steel Temperature Probe or the Vernier Go!Temp. What's included Electrode Support User Manual - ESUP

ISE Ammonium Replacement Module

This module replaces the electrode membrane. Simply unscrew the old one and screw on the new one. The membrane of an Ammonium ISE electrode has a limited life span of one to two years, regardless of frequency of use. Do not order it until you need it, as it will age even when not in use.
