PH value of 7 is a neutral, Less than 7 is acidic (The lower the more acidic), Greater than 7 is an alkaline (The higher the more alkaline)

• 【Quick and Accurate】: Remove the protective cover, immerse the electrode of the pH tester in the solution, press the measurement button, and the reading can be obtained almost immediately. Built-in sensitive electrode sensor, accuracy: ±0.01pH, measuring range: 0-14pH, working temperature: 0℃–60℃, allowing you to quickly and accurately test your liquid.
• 【Automatic Temperature Compensation】: The PH test meter has a built-in (ATC) automatic temperature compensation function, which can accurately determine the pH value of the sample within the range of 0°C-60°C (32°F-140°F), so that the measurement data will not Affected by water temperature.
• 【Automatic Calibration】: It needs to be recalibrated after a long period of inactivity or frequent use. The auto calibration function allows you to calibrate the PH meter easily. Just use the buffer powder and press the “CAL” button to calibrate.
• 【Wide Use】: The lightweight and portable size allows you to easily carry it with you, and measure it anytime, anywhere. It is suitable for testing the pH value of drinking water, liquid food, swimming pools, aquariums, aquaculture, reverse osmosis systems, hot springs, hydroponics, etc. It is very suitable for scientific experiments in children’s schools, testing different bottled water.

Calibration method: 1. Rinse the calibration powder with 250ml distilled water or purified water. The pH electrode was immersed in a mixed phosphate standard buffer solution at pH 4.01 and 6.86 and gently shaken. 2. Press the CAL key for 3 seconds, and 6.86 appears; when the word is flashing, release the hand, the word flashes 3 times and then stops, the calibration is completed; the same analogy is 4.01 and 9.18; until the display value and the standard buffer solution are at ambient temperature The ph value matches. 3. The order of correction is 6.86-4.01-9.18.

How to maintain the pH pen: If you don’t use it for a long time, you can soak the pH pen electrode in pure water in about half a month and insert it in a disposable cup!

Steps: 1. Remove the protective cover. 2. Turn on the switch located on the battery compartment. 3. Insert the pH meter into the liquid to be tested until the liquid is immersed in the “immersion line”. If possible, allow the solution to immerse slightly above the “immersion line”. 4. Gently stir the solution and wait for about two minutes. Read the displayed value. 5, use is complete. Clean the electrode. Turn off the switch. Put on the protective cover.
