Foodcare pH Half-Cell Electrode with BNC Connector - FC260B

Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.

The FC260B half-cell electrode uses low temperature (LT) glass with a spherical bulb and glass body.

Sensing and Reference Half-Cell Electrodes

Every pH electrode is made of two half-cells. The pH sensing portion is known as the indicating half-cell; the other half-cell is known as the reference. The reference half-cell completes the electrochemical cell by supplying a stable voltage that is known, constant, and completely insensitive to the measurement solution.

When both half-cells are in a single probe design , the result is a combination pH electrode. Most pH electrodes used are combination pH electrodes, but half-cells are still desirable for specific applications due to the flexibility of using a unique reference electrodes. There are a variety of reference electrodes including calomel (Hg/Hg₂Cl₂), single ceramic, double ceramic, PTFE sleeve type and flushable.

The HI5315 double junction reference half-cell electrode has a very high flow rate with a plunger design that allows for the reference electrolyte to be easily replaced. The HI5315 can also be disassembled to allow for cleaning of the external junction. The use of the FC260B with a HI5315 is an ideal combination for the measurement of pH in solutions with a high solids content such as dairy products, sauces and other slurries.
