Automatic Calibration- Using the high sensitivity spear probe, you get a full measurement range of 0-14pH with 0.01 pH resolution. Compared with other pH meters, our pH is 5-point calibration method, and equipped with calibration powder, 0.1~60℃ automatic temperature compensation.

Data Transfer and Storage-  Simply dip the pH meter electrode into the solution to be tested and the reading is quickly displayed on the large LCD display. After 5 minutes without any operation, it will automatically enter standby mode to save power, and it can also record data normally. Accurate and real-time Bluetooth data transmission allows you to easily save, manage and share test data. 

Easy to Use- Digital food pH meter with fully customizable parameter settings. The app can set the upper and lower limits of pH, which can be set according to your needs.
