The pH combination electrode consists of three main components: the pH indicator electrode, the reference electrode, and the temperature probe. The pH indicator electrode is responsible for detecting changes in the concentration of hydrogen ions (H+) in the sample solution, which are then converted into a measurable electrical signal. However, this electrode alone cannot provide accurate pH readings without the assistance of a reference electrode.

The reference electrode serves as a stable point of comparison for the pH indicator electrode, ensuring that the measured potential is consistent and reliable. By combining these two electrodes into a single unit, the pH combination electrode simplifies the measurement process and reduces the risk of errors caused by misalignment or improper connection between separate electrodes.

The third component of the pH combination electrode is the temperature probe, which plays a crucial role in ensuring the accuracy of pH measurements. Since the activity of hydrogen ions can be affected by temperature, it is essential to compensate for this variable when calculating the pH value. The temperature probe within the pH combination electrode measures the sample's temperature and adjusts the electrode's slope accordingly, providing a more precise pH reading.

To ensure compatibility with various analytical instruments and setups, the pH combination electrode features a connector that is designed to fit a wide range of equipment. This allows users to easily integrate the electrode into their existing laboratory apparatus without the need for additional adapters or modifications.

With its advanced design and functionality, the new pH combination electrode is expected to become a valuable tool for laboratories, research facilities, and industrial applications where precise pH measurements are critical. Whether for monitoring water quality, analyzing chemical reactions, or ensuring product consistency, this electrode offers a level of convenience and accuracy that was previously unattainable with separate pH indicators and reference electrodes.
