Reference Electrode for ISE Half-Cell Electrode HI5315

Producer: HANNA Instruments

SKU: HANNA-HI5315 Category: Hanna experimental measuring equipment

Reference Electrode for ISE Half-Cell Electrode

The HI5315 is a silver/silver chloride double junction reference electrode half-cell designed for use with ion selective electrodes (ISEs) and pH half-cells.

The reference electrode provides a stable reference voltage when combined with a half-cell sensor. The external reference electrolyte compartment is easily refillable with a quick-release push-in tube design. The reference elements are housed in a durable polyetherimide (PEI) body. The liquid junction is fast-reacting, reusable, and easy to use in the laboratory.

Easy to use with ISE and pH half-cell electrode

The HI5315 is a half-cell reference electrode containing silver/silver chloride (Ag/AgCl) contained in a PEI plastic body. The HI5315 provides contact electrolyte for measuring a potential gradient across a sensing membrane, such as an ISE or pH half-cell.

The Hanna HI5315 reference electrode is designed with a conical junction. The cone in the reference is the liquid-to-sample contact at the tip of the conical junction, providing a stable reference current and a consistent flow rate of electrolyte into the solution. Simply pressing the tip of the electrode allows for easy filling of the electrolyte and replacement when necessary.

For the HI5315 to accurately measure specific ions, the appropriate fill solution must be used in the external fill hole.

When measuring specific ions, the ionic strength of the standard and sample is also important and should be adjusted to a high and constant value with an ionic strength adjustment solution (ISA). The ISA ensures a constant activity coefficient so that the concentration of non-silver ions can be measured. Measuring all solutions with a constant ionic strength reduces the error between measurements.

Outstanding features

Conical joint – The current will be very stable and refillable due to the HI5315 reference electrode’s specially designed conical rim. A narrow ring opening between the electrode’s outer tube and the lower edge of the inner rim of the body creates a highly accurate and stable liquid junction.

Quick release tube – Simply pressing the top cap of the reference electrode quickly pushes the electrolyte out of the body. This design allows for easy cleaning of the electrode or replacement of the filling solution if more than one half-cell sensor is used.

Durable PEI plastic body – The body of the reference electrode is made of durable, chemically inert polyetherimide (PEI) plastic.

Banana connection – HI5315 has a banana connector for easy connection to any meter with a reference probe input.
