ZrO2-based high-temperature and high-pressure pH electrodes are divided into three types (A, B, and C).

Types A and B pH electrodes have a compression fitting and an insertion tube. Type A has an NPT fitting with a metal seal that will be locked to the insertion tube after first use (insertion depth one-time adjustable only). Type B has an NPT fitting with a soft seal that can be repositioned on the insertion tube after each use (insertion depth fully adjustable). The NPT fittings for Types A and B designs are sold separately.

Type C pH electrode has a thread fitting. If the NPT size is 1/4" or larger, a thin-walled protection tube may be provided. Type C design is ultra compact and may be used in autoclaves that have smaller access ports (1/8" or 1/4" NPT). The insertion depth for Type C is fixed at factory (non adjustable).
