High Accuracy pH Meter: This digital pH meter features a built-in sensitive electrode sensor. Simply turn it on, and the pH result appears on the digital screen within seconds. Measures the full pH range from 0.00 to 14.00 with an accuracy of ±0.01. Automatic Calibration Function: The digital pH meter has automatic calibration that adjusts according to water temperature and quality. Obtain accurate pH readings by waiting a few seconds during testing. You can also calibrate the meter using the "CAL" button with calibration buffer powder. Automatic Temperature Compensation: No need to worry about the temperature of the liquid being tested. The digital pH meter includes auto temperature compensation (ATC), which automatically adjusts for variations in water temperature and quality. Wide Application: This water pH meter allows you to measure the acidity and alkalinity of water, helping monitor drinking water quality and maintain optimal pH balance. Ideal for testing drinking water, swimming pools, aquariums, hydroponics, wine, beer, and more. Easy to Use: Remove the protective cap and immerse the electrode into the solution to take a measurement. Eliminates the need to interpret color changes from litmus strips. For prolonged inactivity or after frequent use, recalibrate the tester using the auto-calibration button to ensure accuracy. Material: Plastic Color: Grey Package Contents: 1 x pH Meter Note: Light reflection and differences in display screens may cause slight variations in the color of the item as shown in images. Allowable measurement error is +/- 1-3cm.
