pH 7 Calibration Solution (65ml)

pH electrode calibration fluid pH 7.0 — 65 ml

Standard calibration solution with an accurate pH value of 7.0 for calibrating pH electrodes in dosing and water treatment systems for pools. Used as a neutral calibration point — either separately for a one-point method or paired with a pH 9.0 solution for two-point calibration. Compatible with most standard pH electrodes from various manufacturers.

Specifications:

pH value — 7.0
Volume — 65 ml
Shelf life — 12 months
Storage conditions — dry, cool place, up to +25°C, away from direct sunlight

Frequently Asked Questions

Why calibrate the electrode to pH 7.0 if the normal range for a pool is 7.0–7.6?

pH 7.0 solution is the most important calibration point for pools – it sets the neutral reference point for the electrode scale directly within the operating measurement range. Accurate calibration at pH 7.0 ensures minimal error precisely in the 7.0–7.6 range, which is critical for maintaining water balance.
Is it enough to calibrate only with pH 7.0 without a second solution?

For most pool dosing systems, single-point calibration at pH 7.0 is sufficient for daily operation. Two-point calibration with pH 9.0 is recommended for higher accuracy or if a specific controller model requires it — for example, some CCEI Phileo series dosing systems.
How to properly store an opened bottle?

After use, close the cap tightly and store in a dry, cool place at a temperature not exceeding +25°C away from direct sunlight. Do not return used solution to the bottle — this may contaminate the remaining solution and reduce the accuracy of subsequent calibrations.
