Meytec pH 4.01 Calibration Solution – 20 ml

The Meytec pH 4.01 calibration solution is a certified standard solution intended for calibrating pH electrodes and combination probes used in automatic dosing stations as well as in handheld measuring instruments. The pH value of 4.01 (±0.01 at 25 °C) is internationally recognised as the lower calibration point for pool pH meters.

The 20 ml package is sufficient for several calibrations and is suitable for routine seasonal checks of instruments. The solution is made from analytically pure chemicals and stabilised against temperature fluctuations during storage.

Regular calibration of the pH electrode with this solution ensures accurate readings of the pool water’s pH value, which is a key prerequisite for the correct dosing of chemicals and for protecting bathers’ health.
