Bluelab pH ProbePlus - Replacement pH and temperature probe for Bluelab pH PenPlus

The Bluelab pH ProbePlus is designed as a replaceable measuring module for the Bluelab pH PenPlus and is designed to provide long-term reliability and maximum accuracy in pH measurement. Instead of replacing the entire unit after the electrode wears out, you only need to replace the probe. This reduces costs, minimizes downtime and extends the life of your pH PenPlus.

The probe uses a Double Junction pH electrode , which provides more stable readings and a longer service life compared to standard pH electrodes. This technology reduces the risk of contamination of the reference system and guarantees reliable measurements even with intensive daily use in food solutions.

The built-in temperature sensor allows simultaneous measurement of pH and temperature , ensuring accurate results under various operating conditions. Thanks to the screw fastening system, changing the probe is quick and without the need for tools.

The probe is supplied with a KCl silicone cap with an internal sponge , which keeps the electrode constantly hydrated during storage. With proper maintenance, regular cleaning and periodic calibration, ProbePlus provides long-lasting and reliable performance.

📋 Method of use

1. Unscrew the used probe from the Bluelab pH PenPlus.
2. Screw the new Bluelab pH ProbePlus on until it is snug.
3. Calibrate the probe with the pH 7.0 and pH 4.0 buffer solutions.
4. Rinse the probe with clean water after each measurement.
5. Always store the electrode in the KCl solution, placed in the protective silicone cap.
6. Clean and calibrate regularly for maximum accuracy.

⚠️ Important: pH electrodes are consumables. Over time, their sensitivity naturally decreases. If the readings stabilize more slowly or calibration is difficult, it is recommended to replace the probe with a new one. With proper maintenance and storage , the Bluelab pH ProbePlus provides long-lasting and reliable performance.

💡 Tip from Urban Botaniks: To maximize the life of your probe, use the Bluelab pH Care Kit regularly for cleaning and calibration and never let the electrode dry out. Storing it in KCl solution ensures a longer life and consistently accurate measurements.
