PH Meter Tester, Portable Digital PH Tester Pen 0-14 PH Measuring Range Water Quality Test For Hydroponics Pool

"Wide Use: The digital pH meter has many uses and is very suitable for testing the pH value of pure water, swimming pools, wine, hydroponics, etc. It can be used to test the pH balance in drinking water, aquarium, RO system, spa or hydroponics.

Easy to Use: The pH tester can read very quickly and accurately, convenient for you to judge the data. Turn on the switch, put the probe into the water to stir (make the small glass ball fully contact with the liquid), and read the value after the value is stable.

Wide Measuring Range: The entire measuring range of this digital pH meter is 0.0-14.0 pH, and different data can be obtained. Basically, all environments that need to test the pH value can use the tester to obtain accurate data.

Automatic Temperature Compensation: Don't worry about the temperature of the measured liquid. The pH meter has the function of automatic temperature compensation, it will automatically adjust according to the temperature changes.

Mini PH Pen: The mini PH test pen is small and easy to carry, and can be used for testing at any time, with simple operation. The mini pH meter allows you to easily carry it in your pocket, so you can measure it anytime, anywhere.

Specification: Item Type: pH Meter Material: ABS Purpose: Testing PH Value Battery: LR44 Button Battery Battery Type: Lithium Battery 1-3: Highly Acidic Substance 4-6: Acidic Substance 7: Neutral 8-11: Alkalinity 12-14: Extremely High Alkalinity Package List: 1 x PH Test Machine 2 x PH Reagent 1 x Slotted Screwdriver 1 x User Manual Note: The pH tester should be calibrated frequently, especially after long periods of non-use. PH Test Pen Calibration Method 1. Rinse the calibration powder with 250ml of distilled water/purified water, insert the pH electrode into the mixed phosphate standard buffer solution with a pH value of 6.86, shake it gently, stand still for a while, and wait for the value to stabilize.2. Use the supplied small screwdriver to face the small round hole behind the PH pen, and turn left and right to adjust the calibration potentiometer until the displayed value matches the displayed value of the standard solution at room temperature.3. After cleaning the electrode with distilled water as above, insert the electrode into the potassium hydrogen phthalate standard buffer solution with a pH value of 4.01 for calibration4. Do not contaminate the standard buffer solution after cleaning, and seal it with plastic wrap, which can be reused."
