AC Infinity pH Meter Kit (Model AC-PHM3) Instruction Manual

ແນະນຳ

The AC Infinity pH Meter Kit (Model AC-PHM3) is a high-precision digital instrument designed for accurate measurement of water acidity, alkalinity, and temperature. This device assists in optimizing water quality for various applications, including gardening, hydroponics, aquariums, swimming pools, and general water treatment. Its responsive lithium glass membrane sensor provides instant pH readings with a high accuracy of ±0.1 pH. The meter features an IP-67 rating, ensuring protection against moisture, heat, dust, and sand, and includes a sensor shield for probe safeguarding. The kit comes with 4.00 pH and 7.00 pH calibration solutions to maintain consistent accuracy and support proper probe storage.

1. Unpack the Meter: Carefully remove the pH meter and accessories from the protective carrying case.
2. Probe Hydration: Before first use, and after prolonged storage, soak the pH probe in the provided storage solution for approximately 30 minutes. This hydrates the lithium glass membrane, ensuring optimal performance and accuracy.
3. ລ້າງ Probe: After hydration, gently rinse the probe with distilled or deionized water. Do not wipe the glass membrane, as this can damage it.

ການປັບທຽບ

Regular calibration is crucial for maintaining the accuracy of your pH meter. The AC-PHM3 supports 2-point or 3-point calibration using the included 4.00 pH and 7.00 pH solutions. For best results, perform a 3-point calibration (4.00, 7.00, and 10.00 pH if a 10.00 pH solution is acquired separately) or at least a 2-point calibration (4.00 and 7.00 pH) before each critical measurement session or if readings become inconsistent.

1. Prepare Solutions: Pour small amounts of the 4.00 pH and 7.00 pH calibration solutions into separate, clean containers. Ensure the solutions are at room temperature.
2. ເລີ່ມການປັບທຽບ: Turn on the pH meter. Refer to the meter's display for calibration mode instructions, typically activated by pressing a 'CAL' button.
3. Calibrate with 7.00 pH: Immerse the rinsed probe into the 7.00 pH solution. Allow the reading to stabilize. The meter will typically indicate successful calibration (e.g., a smiley face or 'END').
4. Calibrate with 4.00 pH: Rinse the probe thoroughly with distilled water. Immerse it into the 4.00 pH solution. Allow the reading to stabilize and confirm calibration.
5. (Optional) Calibrate with 10.00 pH: If performing a 3-point calibration, rinse the probe and immerse it into a 10.00 pH solution (not included).

1. ເປີດ: Press the power button to turn on the pH meter.
2. ລ້າງ Probe: Always rinse the probe with distilled or deionized water before and after each measurement to prevent cross-contamination.
3. ເຈາະຮູ: Dip the pH probe into the sample solution you wish to test. Ensure the liquid level is above the sensor bulb.
4. ສະຖຽນລະພາບການອ່ານ: Gently stir the probe in the solution and wait for the reading on the display to stabilize. The meter will typically indicate when the reading is stable.
5. ບັນທຶກການອ່ານ: Note down the pH and temperature values displayed.
6. ອະນາໄມ ແລະເກັບຮັກສາ: After measurement, rinse the probe thoroughly with distilled water and place it back into the storage solution or protective cap.

Understanding the Sensor

The AC-PHM3 utilizes a sensitive lithium glass membrane sensor for rapid and accurate pH detection. This advanced sensor technology allows for quick determination of water's acidity and alkalinity, along with integrated temperature measurement, which is crucial for temperature-compensated pH readings.

Probe ທໍາຄວາມສະອາດ

To ensure accurate and consistent readings, the pH probe should be cleaned regularly, especially after testing samples that may leave residue. Rinse the probe thoroughly with distilled water. For stubborn deposits, a mild cleaning solution specifically designed for pH probes can be used, followed by a thorough rinse.

ການເກັບຮັກສາ

Proper storage is vital for extending the lifespan of the pH probe. Always store the probe with its cap filled with the provided storage solution. Never store the probe dry or in distilled water, as this can dehydrate the glass membrane and lead to inaccurate readings or permanent damage.

Recalibration Frequency

The frequency of recalibration depends on usage and the accuracy required. For critical applications or frequent use, recalibrate the meter daily or every few days. For less frequent use, recalibrate at least once a week or whenever readings appear inconsistent. Always recalibrate after cleaning the probe or if the meter has been stored for an extended period.
