pH 7 Calibration Solution

Essential standardized verification reagent for testing, calibrating, and adjusting pH 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 pH probe several times a year (especially when restarting the pool in the spring) to avoid dosing errors.
