Combination pH Electrodes
The most common pH electrode is the combination electrode, which contains both the reference and the measuring electrode. It's easier to handle one combined electrode than two separate electrodes.

For some specific applications separate glass and reference electrodes are still used. They provide, if managed well, better accuracy for your pH measurement. However, in most cases combined electrodes are accurate enough and much more convenient to use.

Glass Refillable and non refillable pH Electrodes.
Glass body electrodes are capable of withstanding much higher temperatures, up to 100ºC depending on the specific electrode, and also offer chemical resistance to highly corrosive materials or solvents. Glass body electrodes are also easier to clean after use. Either electrode type will require care when handling, as even a small fracture to the bulb or body of the electrode can lead to erroneous readings.



Epoxy refillable and non refillable pH electrodes.
Epoxy body electrodes are more durable, tend to be the more economical choice, and are ideal for environments where rough handling is expected. However, the maximum temperature limit for most epoxy body electrodes is approximately 80ºC.
pH refillable epoxy electrodes are designed for rugged field use.

pH Micro Electrodes
The importance of microelectrodes is widely recognized and interest in their application in diverse areas of research has been increased. Our range of micro glass pH electrodes are designed for measuring pH in small volumes or narrow containers.

pH Flat Surface Electrodes
Our flat surface ph electrodes are ideal for measuring small volumes or moist surfaces, like Agar gel plates, meats, and cheese. They can read viscous liquid samples quickly and accurately without the sample coming into contact with Silver (Ag) ions by using these electrodes.
