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.
