pH Calibration Solutions

• pH 4.0: Acidic solution, ideal for calibrating instruments used in slightly acidic environments.
• pH 7.0: Neutral solution, universal standard for calibration.
• pH 10.0: Alkaline solution, used for calibrating instruments used in basic environments.

ORP Calibration Solution

• ORP 222mV: Standard solution for ORP probe calibration, guaranteeing accurate redox potential measurements.

How to use the solutions:

1. Preparation: Ensure that the electrodes on your instrument are clean.
2. Calibration: Immerse the electrode in the appropriate calibration solution (pH or ORP).
3. Adjustment: Follow the instructions on your instrument to adjust the readings until they match the value in the calibration solution. Rinsing
4. : Rinse the electrode with distilled water between each calibration to avoid cross-contamination.

Please follow the instructions for use and storage to ensure the accuracy and lifetime of the calibration solutions.
