Calibrate once per week if you often test solution of PH 10, or once per half month for neutral solutions. The 250ml calibration solution for multiple uses (10ml or so each time). Then rinse the electrode with pure water before next test. Rinse and rest 3-5 min before conversing from strong acid to strong alkaline and vice versa.

We make your job faster and easier than ever with this convenient PH tester! With the 3-point calibration procedures, your PH testing devicewill automatically identify the calibration solutions to give you your reading in a snap.
▶ 【Automatic Temperature Compensation】
Temperature can affect reading levels, our PH meter's automatic temperature compensation can ensure that you're getting the best possible reading. Unlike other PH metersthat only have a range of 0-50 degree, ours has a even better range of 0-70 degree, so you can test with confidence in any environment.

Tired of squinting at a small screen to get your readings? Enjoy this PH meter's large, backlit LCD screen that displays the information in an intuitive layout so you can still see even in low visibility situations. When the PH value is lower than 3.5 or higher than 12.5, the white digital display will change to red and flash to alert you.

You can easily replace the 2 AAA batteries when it's time, and you can also activate the 15-minute auto-off functionality to save battery. Plus, it even comes with a storage case to keep it safe and protected when you're on the go.
How to Calibrate the PH Meter?
1. Before calibration, prepare 3 beakers separately containing pH4.00 solution, pH6.86 solution, and pH9.18 solution. Make sure that each solution is 250ml and at a stable temperature of 25 degree.
2. Prepare 3 separate beakers with distilled water.
3. Press the ON/OFF button to turn on the meter.
4. Remove the cap and immerse the electrode
into the PH4.00 buffer solution. Stir gently and wait for the value to stabilize.
5. Press and hold the CAL button for 5
seconds. Hold the electrode in the solution until the LCD screen displays a value of pH 4.00.
6. Rinse the electrode with distilled water and blot dry. Repeat step 4, 5, and 6 for the pH 6.86 and pH 9.18 solutions.
