It is applicable to domestic drinking water, hydroponics, laboratories and aquariums._x000D_ _x000D_ 2. Cloud Data Management System: Accurate real-time Bluetooth data transmission, with clear measurement values. Allows you to save, manage, and share test data at your fingertips without worrying about data loss._x000D_ _x000D_ 3. Automatic Calibration of pH Tester: High sensitivity glass probe is used. Compared with other pH meters, pH is a three-point calibration method. Our pH is a five point calibration method and is equipped with calibration powder (pH 4.00, pH 6.86, pH 9.18, pH 7.00, pH 0.01). You can easily calibrate to ensure the accuracy of the measurement._x000D_ _x000D_ 4. Comprehensive Information Display: Just immerse the pH meter electrode in the solution to be measured, and the reading can be quickly displayed on the APP. Multiple parameters are displayed at the same time, and the mobile phone APP controls the backlight display._x000D_ _x000D_ 5. High Precision Water Quality Tester: The high-precision algorithm chip and electrode of our digital water quality tester ensure accurate and fast response. The green backlight LCD design ensures that you can read the measurement results under any conditions._x000D_ _x000D_ _x000D_ Specification: _x000D_ _x000D_ Certification: CE _x000D_ _x000D_ Origin: Mainland China _x000D_ _x000D_ PH value range: 0.1-14.0 Resolution: 0.1ph Precision: 0.1ph Temperature range: 0.1 - 8.0 31.2 - 176 Resolution: 0.1 /0.1 Accuracy: 0.5 EC range: 0-1999us/cm, 10.01-20.0mS/cm, 2000-10000uS/cm Resolution: 1uS/cm 10uS/cm 0.01mS/cm Precision: 2% F.S.
