Tips
consist of 2 mm diameter plastic tubes sealed at one end
with an ion-sensitive membrane. After filling with
electrolyte solution, the user inserts the tube into the
holder and connects it to a pH meter. Tips and holders are
interchangeable, so one tip may be replaced with another
sensitive to a different ion. Replacing a tip takes less
than a minute. Electrode tips normally last several
months, when stored properly in saline solution. When
replacement is necessary, only the tip need be replaced.
Kwik-Tip
electrodes are available separately and as kits -- Each
"KWIK" Electrode Holder kit includes a reusable
holder and three removable tips. In addition to a 4-foot
BNC cable and an electrolyte filling syringe;
"TIP" Electrode Kits contain three electrode
tips for a specific ion. A separate reference electrode,
such as WPI's Dri-Ref, is also required.
If
your pH meter requires a US Standard connector, also order
Part No. 3508 (BNC-to-US pH Standard adapter).
