Температураны автоматтык түрдө компенсациялоо (ATC)
The PHM-230 automatically adjusts pH readings based on the solution's temperature, ensuring accuracy without manual temperature correction.
Red Light Alarm
Image: The Elitech PHM-230 pH meter showing a red light alarm on its display, indicating that the measured pH is either less than 3.5 or greater than 11.5, signifying a strong acid or strong alkaline environment.
When the pH reading is less than 3.5 or greater than 11.5, the meter will emit a red light alarm. This indicates that the environment is strongly acidic or strongly alkaline.
Auto-Off функциясы

The meter is equipped with a 10-minute auto-off function to conserve battery life. If no operation is detected within 10 minutes, the meter will automatically power down. This setting is retained for the next startup.
Калибрлөө
Regular calibration ensures the accuracy of your pH meter. The PHM-230 supports 3-point automatic calibration using standard buffer solutions (pH 4.00, pH 6.86, pH 9.18).

Calibration Procedure (3-Point)
Image: The Elitech PHM-230 pH meter immersed in three separate beakers containing pH 4.00 (pink), pH 6.86 (green), and pH 9.18 (blue) calibration buffer solutions.
- Электр эсептегичте.
- басып, кармап туруңуз КАЛ button to enter calibration mode. The display will show 'CAL'.
- Immerse the electrode (glass bulb fully) into the first standard buffer solution (e.g., pH 6.86).
- Wait for the reading to stabilize. The meter will automatically recognize the buffer and save the calibration.
- Rinse the electrode with distilled water for at least 1 minute.
- Repeat steps 3-5 for the second standard buffer solution (e.g., pH 4.00).
- Repeat steps 3-5 for the third standard buffer solution (e.g., pH 9.18).
- After completing all three points, the meter will automatically exit calibration mode and return to measurement mode. Calibration is saved.

- Always keep the electrode clean. Rinse with distilled water after each use.
- For long-term storage, ensure the electrode is kept moist. The protective cap should contain a small amount of electrode storage solution or pH 4 buffer solution. Do not store in distilled water.
- If the electrode becomes dry, soak it in electrode storage solution or pH 4 buffer for at least 30 minutes before use.
Тазалоо
- Wipe the meter body with a clean, damp кездеме. Абразивдүү тазалагычтарды же эриткичтерди колдонбоңуз.
- If the electrode is contaminated with oil or grease, clean it with a mild detergent solution, then rinse thoroughly with distilled water.
