Product Description

The Bluelab pH 7.0 Calibration Solution is a buffer calibration fluid formulated to exactly pH 7.0, used to calibrate pH meters, probes, and pens so they give accurate readings. Calibration solutions like this are essential for regular maintenance of pH measurement equipment in hydroponics, laboratories, gardening, aquariums, and other applications where accurate pH readings are critical. The pH 7.0 solution serves as the neutral reference point in a standard two-point calibration (pH 7.0 and pH 4.0).

Bluelab calibration solutions are manufactured to high laboratory standards and are often NIST-traceable, which helps ensure calibration consistency and reliability.

• Key Features & Benefits
•  Essential Calibration Standard: Acts as the critical pH 7.0 reference point for instrument calibration — the first step in the common two-point calibration process (pH 7.0 then pH 4.0).
   High-Quality Manufacturing: Formulated to high standards and compatible with Bluelab products and virtually all brands of pH meters and pens.
   Improves Accuracy: Regular calibration with this solution helps ensure consistent and reliable pH readings over time.
   Extends Equipment Life: Keeping your meter calibrated regularly improves performance and helps extend the useful life of probes.

 Usage Notes

• Two-Point Calibration: For most pH meters, calibrate first with the pH 7.0 solution, then with a pH 4.0 solutionto set the slope of the calibration curve.

• Avoid Contamination: Decant a small amount into a clean cup for calibration; do not dip probes directly into the original bottle repeatedly.

• Discard Used Portion: After dipping the probe, discard the used portion — don’t return it to the original bottle
