Note:
1.When the screen displays low power, please replace the battery promptly.
2.The water used to prepare the pH 6.86 and pH 9.18 solutions must be boiled 15 to 30 minutes beforehand to remove dissolved carbon dioxide.During cooling, avoid contact with air to prevent carbon dioxide pollution.

How to use:1.To ensure accurate measurement results, clean the pH electrode before starting the measurement. First, clean it with distilled water, then with the solution to be tested. When taking a measurement, place the pH electrode in the solution, shake it several times, and let it stand for 3 to 4 minutes before reading. The pH measurement error is within the range of ±0.05 pH. During this time, a fluctuation in the value within the error range (the last decimal place) is normal. If there is a large fluctuation after 3 to 4 minutes, the reading time can be extended. The instrument will automatically shut off after 4 minutes without key operation, restart, and continue to observe the change in value. The value will return to the value it was at before the shutdown.2.Instrument Calibration: The instrument must be calibrated at pH 4.00 and pH 9.18 before use. Please prepare the calibration liquid for both calibration points strictly according to the instructions. Measure the temperature of the calibration liquid with a thermometer before starting the calibration and set the temperature to the measured temperature. The greater the temperature error, the more inaccurate the calibration will be, resulting in inaccurate measurement results. Then begin the formal calibration procedure.
