Usage steps:
Step 1: Remove the protective cover, clean the electrode of the pH meter with distilled water, and use filter paper to absorb the moisture attached to and around the electrode.
Step 2: Tap "ON/OFF" to turn on the power, insert the instrument into the tested solution, immerse the tested electrode in the solution, gently shake the instrument to drive away bubbles, wait for the value to stabilize, read the displayed number, and after use, press "ON/OFF" to turn off the power, wash the electrode with clean water, and put on a protective cover.

Calibration steps:
1: Pour 6.86, 4.00, and 9.18 standard buffered saline and distilled water into different clean cups.
2: For precise calibration, each buffer solution is divided into two cups. One cup is filled with clean water to rinse the electrodes, and the other solution is used for calibration.
3: Tap the 'power button' to turn on the power.
4: Place the electrode in a pH 6.86 standard solution and gently shake until the value stabilizes.
5: Press and release the "CAL" button for about 5 seconds, and the instrument will enter automatic calibration mode until the displayed value is consistent with the pH value of the standard buffer solution at that temperature, completing the pH 6.86 point calibration.
6: Clean the electrode and wipe it dry. Place the electrode in a pH 4.00 standard buffer solution and gently shake until the value stabilizes.
7: The measurement methods for PH4.00 and PH9.18 are different from the standard buffer solvent for measuring PH6.86,
Reminder
1: After five minutes of inactivity, the instrument panel automatically shuts down, extending the battery life,
2: The height of the pen tip immersed in the solution should be less than 4CM to avoid affecting accurate readings.
