Hydroponics Accuracy Measurement For Household Drinking Water - A Must Have For Every Home

PH tester 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. 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℃. 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 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) 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. 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. 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! About the battery If the backlight brightness drops significantly or the display value is blurred, the battery should be replaced. When replacing the battery, just pull out the battery compartment and replace it. NoteThe polarity of the battery. A friendly reminder: Regularly cleaning your Ph meter electrode is crucial for ensuring accurate data. Please use the appropriate cleaning solution. 【Mini Size】The mini size ph meter we designed allows you to easily put it in your pocket, so you can take measurements anytime, anywhere. It can help you test it whether you take it to the pool, on a trip, to the beach or camping. The PH meter has an automatic temperature compensation function, which can be adjusted according to the water temperature and water quality.
