???Automatic Calibration?? Our PH meter has an automatic temperature compensation function that can, according to the water temperature and water quality, give pH readings instantly. And you can calibrate the tester with a touch button using the powder buffer. The pH meter should be recalibrated under the following conditions: Used (or placed) for a long time after calibration; Frequent use of electrodes; The measurement accuracy is high.
???Easy to Use?? Compared to the litmus strip, it is convenient to use simply by removing the protective cap that dips the PH meter in the solution, activating the PH using the “ON / OFF” switch. This product includes PH buffer powder. The lifespan of the powder is 2 years.The calibration solution can be reused without contamination. The shelf life after irrigation is approximately 6 months.

Instructions:

Cut the plastic bag, pour the powder into a 250ML volumetric flask, rinse the inner wall of the plastic bag with a small amount of CO2-free distilled water, purified water or neutral water with a pH of about 7, and dilute to the mark and shake it well.

The shelf life of the powder is 2 years.

The calibration solution can be reused as long as it is not contaminated. The shelf life after mixing with water is about 6 months.

After the calibration powder is converted into a calibration solution, follow the steps below ??

How to use the calibration solution:

Wash the electrodes of the pH meter with pure water (2-3 times)

1. Immerse the pH electrode in a mixed phosphate standard buffer solution with a pH of 6.86 (at 25??C) and shake it gently.

2. Press and hold the Xiaozheng button. Don’t let go after the value begins to jump. Keep holding it until the value reaches 6.86, then let go after it stops.

3. Clean the electrode with pure water first, and then insert the electrode into the standard buffer solution of pH4.00 potassium hydrogen phosphate stupid dicarboxylate for calibration.

4. After about two minutes. Compared with the pH value of the buffer solution, the displayed value should be within the allowable error range.

The so-called two-point calibration is to calibrate with two specifications of calibration fluid

Generally start calibration from 6.86 first. Then using 4.00
