The MA911B/2 pH Electrode by Milwaukee Instruments is a laboratory-grade probe designed to deliver precise and reliable measurements in various applications. This electrode is compatible with Milwaukee monitors and controllers, making it ideal for use in laboratories, aquariums, hydroponic systems, and other scenarios requiring accurate pH monitoring.

Main Features:

• Double Junction: The double-junction design reduces the risk of clogging, ensuring longer electrode life and greater reliability.

• Spherical Glass Tip: The spherical glass tip provides the maximum possible surface area, allowing for faster response times during measurements.

• Resin Body: The resin body is resistant to accidental impacts and protects the sensitive glass bulb, enhancing the electrode’s durability.

• Extended Cable: Equipped with a 2-meter (6.6 feet) cable, the electrode offers greater flexibility during measurements, making sample access easier.

Usage and Maintenance:

To ensure optimal performance and prolong the life of the MA911B/2 pH electrode, it is crucial to follow some maintenance practices:

• Storage: Keeping the electrode hydrated is essential. Extended periods of dry storage can compromise the probe’s sensitivity and cause junction clogging. It is recommended to store the electrode in a specific storage solution or pH calibration buffer solutions. Avoid using tap or deionized water for storage, as they can damage the electrode’s sensitivity.

• Cleaning: Residues from samples can affect the sensitivity of the glass bulb and clog the junction. Regular cleaning of the electrode is particularly important if the samples contain organic materials. Periodically soak the electrode in an appropriate cleaning solution to maintain its performance.

• Calibration: Over time, the sensitivity of the pH bulb may decrease. To maintain accurate measurements, it is important to calibrate the electrode regularly, especially after cleaning or extended periods of inactivity.

By following these guidelines, the MA911B/2 pH electrode will provide accurate and reliable measurements over time, meeting the demands of various professional applications.
