• Measurement electrode, also known as the metal electrode

To perform ORP measurements, you have to use this electrode with a reference electrode (see Laboratory Reference Electrodes). The measurement electrode is the electrode sensitive to variations. When used with a reference electrode, it allows you to measure the oxidizing or reducing capacity of a specimen.

• Glass rod whose lower extremity is equipped with a metal part, in this case a platinum rod.
• Recommended for highly oxidizing solutions containing chlorides, redox titrations, etc.

Separate measurement electrodes are recommended for applications in which the life span of the measurement electrode is significantly shorter than that of the reference electrode.

To fully meet your expectations, a range of accessories is available that is compatible with your equipment. Feel free to add them to your quote request to obtain a complete and tailored solution.
