<p>A Digital pH Tester Pen for WaterHow to Use?</p> <p>Step 1: Remove the protective cap</p> <p>Step 2: Clean the electrode in distilled water and let it dry</p> <p>Step 3: Turn the meter on by pressing the ON/OFF key</p> <p>Step 4: Immerse the pH meter electrode in the solution you want to test</p> <p>Step 5: Stir gently and wait for the displayed pH to stabilize</p> <p>Step 6: After finishing, clean the electrode in distilled water and turn the meter off by pressing the ON/OFF key</p> <p>Instructions for use of PH calibration powder:</p> <p>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)</p> <p>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.</p> <p>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. 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.</p> <p>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.</p> <p>Standard configuration：1X PH meter3X calibration powder1X gift box1X instruction manual</p>
