Type3: PH Meter Yellow

Calibration method:
1. Prepare the calibration solution: prepare three containers, and flush out 6.86 4.01 9.18 three packs of calibration powder with 250ML distilled water at 25 degrees Celsius;
2. Remove the electrode protective sleeve;
3. Immerse the electrode in the temperature of pH 6.86 standard buffer solution (25 ℃), and gently stir in the solution to drive off bubbles around the electrode;
4. After the number is stable, press the "CAL" on for 5 seconds (the instrument enters the automatic calibration state), then the value will flash, showing 6.86 digits;
5. Staying for about ten seconds, the value is not flashing, it means the calibration is completed;
6. Wash the electrode and dry filter paper with distilled water;
7. Immerse the electrode at a temperature of pH 4.01 standard buffer solution (25°C), and gently stir in the solution to drive off bubbles around the electrode;
8. After the numbers are stable, press the "CAL" on for 5 seconds (the instrument enters the automatic calibration state). At this time, the value will flash and display 6.86 digits. Press the "CAL" on again, and 4.00 digits will be displayed;
9. Stay for about ten seconds, the value is not flashing, it means the calibration is completed;
10. Wash the electrode and dry filter paper with distilled water;
11. Immerse the electrode in the temperature of pH 9.18 standard buffer solution (25℃), and gently stir in the solution to drive off bubbles around the electrode;
12. After the numbers are stable, press the "CAL" on for 5 seconds (the instrument enters the automatic calibration state). At this time, the value will flash, displaying 6.86 digits, and then press the "CAL" on twice, and 9.18 digits will be displayed;
13. Stay for about ten seconds, the value is not flashing, it means the calibration is completed;
14. Clean the electrode and dry filter paper with distilled water;

How To Use :
1. Remove protective cap.
2. First rinse the electrode with distilled water and suck it with filter paper.
3. Turn the meter on by pressing “ON/OFF” key.
4. Immerse the pH meter electrode in the solution to be tested (should not be over the immersion line).
5. Stir gently and wait around 30 seconds till the reading stabilizes.
6. After finishing, clear the electrode with pure water, turn the meter off by pressing “ON/OFF” key.
7. Always replace the protective cap after use.

Steps :
1. Turn on PH meter
2. Disolve each buffer solution in 250ML of distilled water
3. Immerse the electrode into the PH 6.86 solution,(under the temperature of 25)
4. Press the “CAL”(calibration)on for 5 seconds and release
-Display will start flashing 6.86
-Wait until the display stops flashing.
Rinse the electrode with distilled water and dry it with filter paper.

5. Immerse the electrode in PH 4.00 solution,
-Press“CAL”on for 5 seconds,then press and release immediately second time
-Reading will start flashing 4.00
-Wait until display stops flashing
Rinse and dry the electrode with distilled water as before.

6. Place the meter back to the buffer solution to test calibration.If incorrect,please repeat the calibration

7. If approximate PH of your test solution is known to be above 7.0,calibrate the meter using 6.86 and 9.18 solution. To do this,please follow the calibration chart,The third step is the calibration method for 9.18 point.
