【Easy to Use】 Remove the protective cap and turn on the pH meter by pressing the "ON/OFF" button. Immerse the electrode in the test solution, stir gently, and wait for the reading to stabilize. Once finished, clean the electrode with distilled water, turn off the pH meter, and replace the protective cap.

【High-Precision pH Meter】 The pH meter uses a sensitive glass bulb electrode sensor that can quickly and clearly read accurate pH values within the measuring range of 0-14.0.

This precise pH tester kit (0.01 resolution) is so accurate that it can test a pH within ±0.02. [Auto Calibration] The pH meter features an auto-calibration function that can be adjusted according to the water temperature and quality. The pH reading can be obtained after waiting a few seconds during the test. Additionally, you can calibrate the tester with the one-touch "CAL" button using the calibration buffer powder. [Automatic Temperature Compensation] The product provides comprehensive pH measurements from 0-14 with temperature compensation for more accurate results. The test liquid temperature can range from 0°C to 60°C (32°F to 140°F). [Versatile Application] Easily fits in your pocket or bag and goes anywhere. The pH meter is an ideal option for families and laboratory testing of pH values, suitable for testing the pH balance of drinking water, swimming pools, aquariums, RO systems, spas, or hydroponic systems; appropriate for a wide range of applications.
