Understanding ORP Measurement:ORP (Oxidation-Reduction Potential), also called redox potential, measures the ability of a solution to oxidize or reduce substances. Positive ORP values indicate oxidizing conditions (common in chlorinated water), while negative values indicate reducing conditions. ORP measurement is critical for monitoring water treatment effectiveness, sanitizer levels, and chemical process control.Why Choose Double Junction?The double junction design provides an additional barrier between the reference electrolyte and your sample, preventing contamination and extending probe life—especially important when testing samples with high protein content, heavy metals, sulfides, or other interfering substances that can poison single-junction probes. This makes the SE300 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 in place. Keep the platinum sensing element clean and free from deposits. Regular calibration with ORP standard solutions ensures optimal accuracy.Note: MW500 PRO meter sold separately. Regular calibration with ORP standard solutions (e.g., 200 mV, 470 mV) recommended for optimal accuracy.
