It can be used as a classic tester even if it is not connected to a smartphone.It can be used as a classic tester even if it is not connected to a smartphone. Cloud-Based Data Management SystemAccurate real-time Bluetooth data transmission and clear measured values make it easy for you to save, manage and share test data without worrying about data loss. Automatic Calibration pH TesterWith high sensitive glass probe, you can get a full measurement range of 0-14pH, 0.01 pH resolution. Compared with other pH meters, the pH is a 3-point calibration method, and our pH is a 5-point calibration method and equipped with a calibration powder (Asia Standard: pH 4.00, pH 6.86, pH 9.18, and EU Standard: pH 7.00, pH10.01), you can calibrate effortlessly to ensure the accuracy of your measurements. Comprehensive Information DisplaySimply immerse the pH meter electrode in the solution to be tested, readings are quickly displayed on a large LCD display. multi-parameter display at the same time, mobile phone APP control backlight display. Easy to UseDigital pH meter fully customizable parameter settings. the App can set the upper and lower limits of pH, which can be set according to your needs. when the value you set exceeds the test range, the App interface will display a red value abnormally, notifying you of any values exceeding your preset range. _x000D_
