222mV ORP Calibration Solution

This is a standard 222mV oxidation-reduction potential (ORP) calibration solution for use with compatible ORP meters. The solution is supplied in a plastic container. It is designed specifically for single-point calibration of ORP testers to ensure accurate mV readings. Store in a cool, dark place below 25°C, away from direct sunlight and carbon dioxide exposure; keep container tightly sealed to prevent photochemical degradation and contamination. Not intended for refrigeration. Includes one unit of 222mV ORP calibration solution only — no meter or accessories included.
