Spare ORP Electrode for HI981406 – HI3214P

The HI3214P brings the ability to test ORP to any user at an affordable price. The polyetherimide (PEI) body protects against accidental breakage while the spherical glass tip is perfect for aqueous samples due to the large surface area. Suitable for samples from 0 to 80℃ (32 to 176℉), this electrode is perfect for any general agriculture application with the HI981406 meter.

  • PEI body offers increased durability
  • Cloth junction protects against clogging
  • Universal BNC connector makes this the perfect replacement electrode


PEI Body

The body of the HI3214P is composed of polyetherimide (PEI), suitable for a wide range of applications and ideal for field measurements. 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

The renewable cloth junction lets the user refresh the electrode junction by extracting a small portion of the cloth from the electrode to clear clogging, essentially creating a new junction.

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.
