Frequently Asked Questions

Why are multiple pH calibration points necessary?

Multi-point calibration ensures accuracy across the measurement range. Using calibration points at pH 4, 7, and 9-10 accounts for meter response variations and provides reliable measurements throughout typical laboratory pH ranges.

What does NIST certification mean?

NIST (National Institute of Standards and Technology) certification guarantees that the pH values are traceable to international standards and have been independently verified for accuracy.

How should these solutions be stored?

Store solutions in a cool, dark place at controlled temperature. Ensure bottles are tightly sealed to prevent evaporation and contamination. Check expiration date before use.

Can these solutions be reused?

Solutions should be used once for calibration. Reusing calibration solutions can lead to contamination and inaccurate measurements. Always use fresh solution for each calibration cycle.

Why is temperature control important?

pH values are temperature-dependent. These solutions are calibrated at 25°C. Significant temperature variations can affect pH accuracy, so maintain consistent temperature during calibration.
