Zodiac - pH Buffer Solution Kit 6x pH 4 and 6x pH 7 Sachets - R0824400

Zodiac – pH Buffer Solution Kit 6x pH 4 and 6x pH 7 Sachets

The Zodiac pH Buffer Solution Kit (R0824400) is a genuine calibration consumable containing 12 single-use sachets — 6 x pH 4.01 and 6 x pH 7.01, each holding 20 ml of precision reference solution. It is designed to perform accurate two-point calibration of pH sensors used in Zodiac pH dosing and control systems, ensuring your pool water chemistry is measured and managed correctly.

Compatibility

This kit is the official replacement for legacy reference W013002 and is specified across a wide range of Zodiac / Fluidra pH management equipment, including the pH Perfect, pH Expert, pH Clever, pH Link, Dual Link, and GenPH systems (Fluidra exploded views W500702, W500708, WW000031, WW000176, WW000177, and WW000253). It is suitable for any Zodiac pH sensor that requires two-point calibration at pH 4 and pH 7.

Why genuine matters

Accurate pH dosing depends entirely on a correctly calibrated sensor. An uncalibrated or poorly calibrated probe can produce readings that are off by 0.5–1.0 pH units, leading to over- or under-dosing of pH corrector, resulting in eye and skin irritation, cloudy water, or accelerated equipment wear. Genuine Zodiac buffer solutions are formulated to the precise reference values required by Zodiac controllers, ensuring reliable calibration every time. The individual sealed sachets preserve solution integrity right up to the moment of use — critical for an accurate calibration result.

Installation

Calibrate with pH 7 first to set the zero point, then rinse the probe and use the pH 4 sachet to set the slope point. Open only what you need: each sachet is a single-use portion — discard any unused solution after calibration. Follow your specific Zodiac controller’s calibration procedure as detailed in the product manual. Regular calibration is recommended at each sensor replacement and periodically throughout the swimming season.
