Calibration:
1. Turn on the pH meter.
2. Dissolve each buffer solution in 250 ml of distilled water.
3. Immerse the electrode into the pH 6.86 solution (under the temperature of 25℃).
4. Press the “CAL”(calibration) button for 5 seconds and release；
- Display screen will start flashing “6.86”；
- Wait it until the display screen stops flashing；
- Rinse the electrode with distilled water and make it dry with filter paper.
5. Repeat the above steps with 4.01 pH buffer powder and 9.18 pH buffer powder.
Note:
Calibration is required in the following conditions.
- Lengthy periods of inactivity
- Very frequent use
- The testing accuracy requirement is very high
- The “cal” key was pushed and electrode exposed to air for extended period of time

---------------- pH Test Strips ----------------
PH Color Chart Intervals: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14
pH < 7 is acidic, pH = 7 is neutral, pH > 7 is alkaline
Instructions:
1. Take one strip from the pack and dip it into the solution you would like to measure. The color of your strip will change immediately.
2. Quickly match this color against the color chart on the inside of your pack to obtain the pH. Do not wait or let the strip dry!
3. The number next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutral.
Please note that solutions with a pH of ~5.5 will result in a yellow colored test strip that resembles the original color of the dry strip.
Store in a cool, dry place away from sunlight.
