Calibration Solution pH 7.01
Ready-to-use buffer solution with a defined pH value of 7.01 for calibrating pH meters and measuring electrodes.
Why do you need a pH calibration solution?
pH electrodes change their measuring behaviour over time and depending on use (drift, ageing, contamination). To keep readings reliable, pH meters must be calibrated regularly against solutions with an exactly known pH value. The pH 7.01 calibration solution provides this defined reference value.
How do you calibrate with it?
The electrode is immersed in the buffer solution and the reading on the device is adjusted to the setpoint of 7.01. For higher accuracy, a two- or three-point calibration with several buffer values is recommended (typically pH 7.01 as the zero point plus pH 4.01 and/or pH 10.01).
- Defined reference value pH 7.01
Reliable basis for accurate pH measurements
- Universally applicable
Suitable for all common pH meters and measuring electrodes
- Regular calibration
Ensures consistently accurate and reproducible results
- Ready to use
Ready for immediate use – no preparation or dilution required
- Rinse the pH electrode with distilled water and dab it dry carefully
- Pour a small amount of calibration solution into a clean container (do not measure directly in the storage bottle)
- Immerse the electrode in the pH 7.01 solution and allow the reading to stabilise
- Calibrate the pH meter to the setpoint of 7.01
- For a multi-point calibration, repeat with additional buffer values (e.g. pH 4.01 and pH 10.01)
- Rinse the electrode after calibration
Tip for best results
Use the solution at room temperature if possible (approx. 25 °C) and discard the portion taken after use – never pour it back into the storage bottle. This keeps the reference solution uncontaminated.
Important notes
- Reseal the bottle immediately after use
- Observe the best-before date – use up opened solutions promptly
- Store in a cool, dry place away from light
