Why Choose Double Junction?The double junction design provides an additional barrier between the reference electrolyte and your sample, preventing contamination and extending electrode life—especially important when testing samples with high protein content, heavy metals, sulfides, or other interfering substances that can poison single-junction electrodes. This makes the SE220 ideal for demanding applications where measurement accuracy and probe longevity are critical.Maintenance & Care:The gel-filled reference system requires minimal maintenance—no refilling needed. Store the probe with the protective cap filled with storage solution to prevent the glass membrane from drying out. Clean the junction regularly to prevent clogging and maintain response time. Regular calibration ensures long-term accuracy and reliability.Note: MW101 and MW102 meters sold separately. Regular calibration with pH 4.01, 7.01, and 10.01 buffer solutions recommended for optimal accuracy.
