pH Electrode for use with HI8314


The HI1217D is a PEI body, single ceramic junction pH electrode with a DIN connector. This design consideration is ideal general purpose laboratory use.

•  Great for general purpose laboratory use
•  Made for use use with the HI8314 pH meter.
•  No need to refill electrolyte.

  The HI1332B uses general purpose (GP) glass, spherical bulb, polyetherimide (PEI) body, single ceramic frit, and double junction.
General Purpose Glass Formulation
•  The measurement of pH at very high temperatures is detrimental to the sensitive glass bulb and will shorten the life of it.
•  A pH electrode with general purpose (GP) glass will have a resistance of 100 megaohms at 25°C while the resistance of LT glass is around 50 megaohms at 25°C.
•  As the temperature of the glass decreases in the sample, the resistance of the LT glass will approach that of GP glass.
•  If using GP glass, the resistance would increase above the optimum range, resulting in increased impedance and ultimately affecting the measurement.
•  The HI1332B is suitable to use with samples that measure from 0 to 70°C.

  Spherical Bulb
•  The spherical bulb is for general purpose use.
•  Other tip shapes include conic for penetration and flat tip for surface measurements.

  PEI Body
•  The body of the HI1332B 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.

  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.

  DIN Connector
•  The HI1217D uses a DIN connector.
•  This type of connector is made only for the HI8314 pH meter.
•  Other type of connectors include BNC, screw type, T-type, and 3.5mm to name a few.
•  These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.
