Features: [BlueTooth PH Meter]Professional Bluetooth PH meter and intelligent connection with APP, Full measure range: 0.00~14.00, Accuracy up to 0.1ph. [Set Measure Limit]Digital pH can be set with custom parameters. The app can set the upper and lower limits of pH, which can be set according to your own needs. When the value you set is out of the test range, the App interface will display a red value abnormally to you of any value that is out of the preset range. [Automatic Temperature Compensation]PH tester has an automatic temperature compensation function(0.1C~60.0C), which can decrease the error caused by the change of liquid temperature. [ High-precision Puncture Electrode ]The glass electrode can measure the PH value of care products, creams, lotion, cosmetics, etc. responds quickly, measures accurately, and is corrosion-resistant, and the electrode can be replaced for easier maintenance. [Wide Applications]Suitable for care products, creams, lotion, cosmetics, etc, and other Solid and semi-fixed sample PH value testing.
