Prior to Use
•Remove the electrode protective cap from the tester.
•If the glass sensitive membrane on the electrode dries out, soak the electrode in 3M KCL solution or tap water for at least 15 minutes. DO NOT use
distilled or deionized water, it will render the electrode useless.
Preparing the pH Buffer Solutions
•Open the pH7.00 buffer packet, place the reagent into a 250ml volumetric flask. Pour the distilled water 250ml to scale line, mix the solution until the
reagent is completely dissolved.
•Preparation of pH4.01 and 10.01 standard buffer solutions are the same as above. Prepared standard buffer solutions should be stored in hermetically
sealed glass containers.
Switching the Tester On and Off
•Press the Meas key to switch on the tester, the display shows measured value.
•Press and hold the Meas key for 5 seconds, the tester will switch off.
•If you do not press any key for 8 minutes, the tester will automatically switch off to conserve energy.

pH Calibration
PHscan10L pocket pH tester must be calibrated prior to first use or new electrode replaced. To ensure accuracy, regular calibration is recommended. DO NOT
reuse the pH buffer solution after calibration, contaminants in solution will affect the calibration and eventually the accuracy of the measurement.
1. Rinse the electrode with distilled water. Press and hold the Cal key for 3 seconds, the display
shows CAL 7-4. If necessary, press the Cal key again, the display shows CAL 10-7.
2. Select the pH buffer option you require. Press the Enter key, the tester shows first calibration
point, pH7.00.
3. Place the electrode into the pH7.00 standard buffer solution, the end of the electrode must be
completely immersed into the calibration solution. Stir the tester gently to create a
homogeneous solution.
4. Press the Enter key, the tester begins the calibration. Wait for the reading to stabilize, the
calibration value will flash three times indicating that the first calibration point is completed.
The display automatically shows CAL 4 or CAL 10.

5. Rinse the electrode with distilled water. Place the electrode into the pH4.01 (or 10.01)
standard buffer solution. Stir the tester gently.
6. Press the Enter key. Wait for the reading to stabilize, the calibration value will flash
three times and the CAL icon disappears from the display. Calibration is completed.
If you want to exit the calibration, press the Meas key, the tester will immediately return
to the measurement mode.
pH Measurement
•Rinse the electrode thoroughly with distilled water.
•Place the electrode into the sample solution, stir the tester gently.
•Record the measured value when the reading is stable.
Data Hold
During the measurement, press the Hold key, the tester immediately locks the displayed value, the icon appears on the display. Press the key again
to resume measuring.
Electrode Care and Maintenance
•For best results, please always keep the glass sensitive membrane wet.
•Ensure that the electrode is thoroughly washed with distilled or deionized water after use.
•If you do not use the tester for long periods, store the electrode into the 3M KCL solution.

Electrode Replacement
When the tester fails to calibrate or gives fluctuating readings for calibration standards, you need to replace the electrode.
1. Twist the electrode collar counter clockwise, pull the old electrode away from the tester.
2. Align the slot on the new electrode, gently push the electrode into the tester.
3. Twist the electrode collar clockwise until it is tight. Installation is completed.
Troubleshooting
LCD DISPLAY
CAUSE
CORRECTIVE ACTION
Electrode dried out
Soak the electrode in 3M KCL solution at least 20 minutes.
Measured value is out of range
Check the electrode whether clogged, dirty or broken.
Incorrect pH buffer solutions
Using the fresh pH buffer solutions for calibration.
Electrode is broken
Replace the electrode.
pH Electrode Selection Guide
PHscan10L pocket pH tester installed with a long-reach pH electrode that is used to measure the pH of the small volume samples. If this electrode can not
meet your measurement requirements, please refer to the table below to select an applicable sensor.
