Product description
PH usage related issues:
- When the PH meter is turned on in the air, the value jumps irregularly, which is a normal phenomenon. The value in the air cannot be used as a reference.
- When measuring the water with the PH meter, it needs to be stirred gently (to remove the bubbles attached to the probe), and it takes a period of stabilization. It is normal for the value to jump up or down during the test. Please do not just insert it and read it immediately.
- White crystalline salt appears around the electrode of the PH meter, which is a normal phenomenon of the PH electrode, and the electrode can be removed by immersing it in water and cleaning.
- The PH meter electrode is made of glass, which is fragile. Please do not drop it or touch it with your hands. Do not test the water above 50℃. Do not test the strong acid and alkali, which will cause the electrode glass to burst.
Product name: 0.01ph automatic calibration ph pen
Test item: water ph value
Working environment: 0-80℃, RH<95%
Measuring range: 0.00-14.00ph

How to use:
- Take off the pen cover and clean the electrode with pure water
- Put the pen probe into the solution, taking care not to exceed the water level
- Turn on the switch, stir gently, and wait for the reading to stabilize
- After the reading is stable, read the displayed value
- After the test, clean the electrode with pure water, dry the water on the pen tip in time, and cover the pen cover back
Standard configuration：
- 1XPH meter
- 3X calibration powder
- 1X gift box
- 1X instruction manual
Pay attention to the calibration sequence (6.86-4-9.18)
Precautions:
Please note that the PH pen probe is a glass product and is a fragile product. Please do not collide with things. Once the damage is not replaceable, you must protect the probe. After use, use absorbent paper to gently absorb the water on the probe.
Instructions for use of PH calibration powder:
Calibration powder:pH standard solid substance. It can be used after adding water. Suitable for calibrating any type of ph meter. Each package needs to prepare 250ML of purified water.
(Note that the configured water must be purified water or distilled water. Tap water and mineral water cannot be used to configure the calibration solution.
The water must be added in the required proportion, otherwise it will affect the accuracy of the calibration and increase the error)
- The configured calibrators shall be sealed with clean bottles and stored in a cool place away from light.
- The shelf life of the calibration powder is 2 years, and the shelf life of the calibration solution after configuration is 6 months
Matters needing attention:
PH meter has been calibrated before delivery, the buyer does not need to re-calibrate after receiving the goods!
In the following cases, the PH meter must be re-calibrated:
- Has been used for a long time after calibration;
- Special electrode use Frequently;
- The measurement accuracy requirements are relatively high.
About the battery
