Description

The HI769828-0 is a PEI plastic body, double junction, gel filled pH electrode. This pH/ORP electrode is made for the HI9828 multiparameter portable meter. The electrode has a rugged PEI (polyetherimide) body that offers excellent chemical resistance in an unbreakable plastic making it ideal for field and industrial applications.The HI769828-0 has a glass pH sensing tip with a Ag/AgCl reference electrode in gel electrolyte. Each module is color coded for easy installation into the appropriate probe

PEI Sensor Body
The PEI (polyetherimide) electrode 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 harsh chemicals.
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.
Cloth Junction
This type of junction is often used on electrodes with gelled electrolytes. The advantage of this junction is it is renewable; as the cloth-like material is pulled out from its position, the junction is renewed with an uncontaminated, fresh surface.
Color Coded Sensor
Sensors are color coded to match sensor ports on the probe for quick, field-replaceable, screw-type, connection and identification.
