ORP Tester

ORP testers measure the potential difference generated by electron transfer between an electrode and a solution, reflecting the solution's oxidation-reduction capacity. Their core components include a precious metal electrode and a reference electrode, with the potential value directly indicating the tendency of substances to gain or lose electrons. They are used in fields such as water quality monitoring, wastewater treatment, and swimming pool disinfection to assess the direction of chemical reactions.
Selection
When selecting, pay attention to the electrode material—platinum electrodes are suitable for most scenarios. Consider temperature compensation functionality to adapt to environmental changes. Check the protection rating; outdoor use requires a dustproof and waterproof design. The calibration method should be simple and quick. The measurement range should cover the common ±2000 mV range. The cost of use is influenced by the supporting reagents and electrode lifespan.
