Spare pH Electrode for HI981406 (2m)

PEI Body

The body of the HI2114P is composed of polyetherimide (PEI) resin. The PEI body is suitable for a wide range of applications and excels in field measurements due to its durability. The shielding around the spherical glass tip minimizes breakage due to accidental bumping or dropping of the electrode. The PEI plastic is a high quality plastic that is chemically resistant to many aggressive chemicals.

Cloth Junction

With a renewable cloth junction, the HI2114P has an extended life over typical pH electrodes. A normal junction clogs with use over time and a typical electrode would normally have to be thrown away once the junction becomes contaminated. the HI2114P junction is 2 cm long and when dirty, can be pulled out to expose a fresh section to effectively renew the electrode's life.

Double Junction Reference

A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or silver precipitates on the junction are likely to form.

Multi-pin Connector

The HI2114P uses a multi-pin connector for a tight connection and has a sleeve to protect from spills.
