The durable electrode is unbreakable and does not clog like traditional glass bulb sensors. The easily replaceable sensor is ideal for field or laboratory use. With 2- or 3-point calibration, the device automatically recognizes and reports buffer solutions and the percentage of saturation (PTS), indicating when it is time to replace the electrode.

The set includes a flat surface pH electrode, a protective cap, and two 3V CR-2032 button batteries. pH buffer solutions are required for calibration and are sold separately.
