4. Product Overview

This image shows the HFCCYBGS PH220 Pen-Type pH Meter. The device is white and gray, with a digital display showing a pH reading of 8.7 and a temperature reading of 28.5. Below the screen are three buttons: 'CAL' for calibration, 'HOLD' for data hold, and a power button with a universal power symbol.

The PH220 features a clear digital display for simultaneous pH and temperature readings. It includes dedicated buttons for calibration (CAL), data hold (HOLD), and power on/off. The built-in electrode is located at the bottom, protected by a removable cap.

5. Setup

5.1 Battery Installation

1. Locate the battery compartment, typically at the top or back of the meter.
2. Open the compartment cover.
3. Insert four (4) 1.5V batteries, ensuring correct polarity.
4. Close the battery compartment securely.

5.2 Initial Preparation

• Remove the protective cap from the electrode.
• Rinse the electrode with distilled water before first use and after each measurement.

6. Operation

6.1 Power On/Off

Press the Power button (marked with ⏻) to turn the meter on or off.

6.2 Taking Measurements

1. Ensure the meter is clean and calibrated.
2. Immerse the electrode into the sample solution, ensuring the sensor is fully submerged.
3. Gently stir the meter to remove air bubbles and allow the reading to stabilize.
4. Read the pH and temperature values displayed on the screen.

6.3 Data Hold Function

Press the HOLD button to freeze the current reading on the display. Press it again to release the hold and resume live measurement.

7. Calibration

Regular calibration ensures the accuracy of your pH meter. The PH220 supports a three-point calibration process.

7.1 Calibration Procedure (Three-Point)

1. Prepare standard buffer solutions of pH 4.0, pH 6.9 (or 7.0), and pH 9.2. Ensure the buffer solutions are at approximately 25℃.
2. Turn on the meter and rinse the electrode with distilled water.
3. Immerse the electrode into the pH 6.9 (or 7.0) buffer solution.
4. Press and hold the CAL button until the display shows "CAL" or a similar calibration indicator. The meter will automatically recognize the buffer and calibrate.
5. Once the first point is calibrated (usually indicated by a stable reading or a confirmation message), rinse the electrode with distilled water.
6. Immerse the electrode into the pH 4.0 buffer solution. Press CAL again to calibrate the second point.
7. Rinse the electrode with distilled water.
8. Immerse the electrode into the pH 9.2 buffer solution. Press CAL again to calibrate the third point.
9. After successful three-point calibration, the meter will typically return to measurement mode.

Note: Always calibrate with fresh buffer solutions. Discard used buffer solutions after calibration.

8. Maintenance

8.1 Electrode Cleaning

• After each use, rinse the electrode thoroughly with distilled or deionized water to prevent contamination.
• Do not wipe the electrode bulb, as this can cause static electricity and damage the sensitive glass membrane. Gently blot dry with a lint-free tissue if necessary.
• For stubborn deposits, refer to specialized electrode cleaning solutions.

8.2 Storage

• Always replace the protective cap on the electrode when not in use.
• Store the electrode in a suitable electrode storage solution or a pH 4 buffer solution. Never store dry.
• Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.

8.3 Battery Replacement

When the display becomes dim or the meter fails to power on, replace the batteries as described in Section 5.1.

9. Troubleshooting

• Inaccurate Readings:
  • Ensure the meter is properly calibrated.
  • Check if the electrode is clean and free from deposits.
  • Verify that the buffer solutions used for calibration are fresh and correct.
  • Ensure the electrode is fully submerged in the sample.
• No Display/Meter Not Turning On:
  • Check battery installation and replace batteries if necessary.
  • Ensure the battery compartment is securely closed.
• Slow Response Time:
  • Clean the electrode as described in Section 8.1.
  • Ensure the electrode is properly hydrated (stored in solution).
