PH standard solution, reagent buffer solutionProduct Introduction:

A pH buffer solution is a solution that can maintain a stable pH value. If a small amount of acid or base is added to this solution, or if a chemical reaction in the solution produces a small amount of acid or base, and the solution is appropriately diluted, the pH value of this solution is basically stable and unchanged. This solution that can resist a small amount of acid or base or dilution and make the pH value less likely to change is called a pH buffer solution.

This solution is non-toxic, non corrosive, non polluting, and poses no harm to the product.

Purpose: PH buffer solution is used to calibrate the accuracy of electronic pH testing pens. The electronic pH testing pen has high accuracy, but over time, the detection results may deviate. Therefore, during use, the testing pen should be regularly calibrated.

PH standard solution, reagent buffer solutioninstructions:

Clean the electrode of the acidity meter with pure water (2-3 times), then immerse the electrode in the calibration solution and adjust the pH value of the acidity meter to the same value as the calibration solution.

If you want higher instrument accuracy, you can use two-point or three-point calibration.

Calibration with three different specifications of calibration solution. The so-called two-point calibration refers to using two types of calibration solutions for calibration, while three-point calibration refers to using. Usually, calibration starts from 6.86. Then use either 4.00 or 9.18.

In the following situations, the pH meter needs to be recalibrated:

1. Used (or left for a long time) after calibration;

2. The electrode is used frequently;

3. High measurement accuracy is required;

4. After replacing the electrode (for pH meters with replaceable electrodes)

Storage: Store at room temperature. If turbidity, mold, precipitation, or other phenomena are found, discard the solution and do not continue to use it!
