468mV Rx Calibration Solution

Essential standardized verification reagent for testing, calibrating, and adjusting Redox (ORP) probes in automatic pool, spa, or laboratory controllers.

Usage & Storage Instructions

Shelf Life: When stored correctly at room temperature and protected from light, a sealed bottle will last approximately 2 years.

Golden Rule: Never re-immerse a dirty probe directly into the bottle, and never pour used liquid back into the original bottle to avoid contaminating the reagent.

Frequency: It is recommended to calibrate your Redox probe several times a year (especially when restarting the pool in the spring) to avoid errors in chlorine or bromine dosage.
