Buffer solution for calibration pH 7.00 - 20 ml - 7031424

Buffer solution for calibration pH 7.00 – 20 ml

Precisely formulated at pH 7.00, this ready-to-use 20 ml buffer solution provides a reliable neutral reference point for calibrating pH electrodes and probes used in automated pool water treatment systems. The single-use sachet format ensures a fresh, uncontaminated solution every time, eliminating the variables that come with shared bottles. It is an essential maintenance consumable for any pool installation equipped with an automated pH dosing or salt-chlorination controller.

Calibration accuracy & probe care

pH 7.00 sits at the heart of the swimming pool’s target water balance range, making it the most practical single-point calibration reference for pool pH probes. Regular calibration with a traceable buffer solution confirms whether an electrode is responding correctly, allowing technicians to identify drift or electrode degradation before it leads to inaccurate dosing. Using a fresh 20 ml sachet each time removes the risk of cross-contamination or pH drift that can affect repeatedly opened buffer bottles.

Compatibility & use in automated systems

This buffer is compatible with the pH electrodes fitted to the vast majority of automated chlorination and pH-control units — including ORP/pH combined probes commonly found on salt-chlorination and liquid-dosing systems. To calibrate, the probe is rinsed, immersed in the buffer solution, and the displayed value is confirmed or adjusted in the controller’s calibration menu. The compact 20 ml volume is well-suited to on-site service visits where carrying large bottles is impractical.

Storage & handling

The sealed sachet protects the solution from atmospheric CO₂ absorption, which can shift pH readings over time in opened containers. Store in a cool, dry location away from direct sunlight, and use the full contents immediately upon opening to obtain the most accurate calibration result. Basic precautions — avoiding contact with eyes and skin — apply when handling any pH buffer chemical.
