ORP (Redox=Chlorine) platinum electrode with cloth junction

PEI Body

The body of the HI3214P 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 HI3214P has an extended life over typical ORP 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. 

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.

BNC Connector

The HI3214P uses a BNC connector. This type of connector is universal in that it can be used on any pH meter that has the female BNC probe input.
