6 In1 Water Quality Detector Smart Online Bluetooth Water Chlorine Meter Ph Meter Powered Tool For Feature: 1.6-in-1 Meter Bluetooth-compatibility: by mobile applications, it can professionally measure pH, ORP, chlorine, EC, TDS and temperature. It is applicable to domestic drinking water, hydroponics, laboratories and aquariums. 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. 3.Automatic Calibration of pH Tester: High sensitivity glass probe is used. Compared with other pH meters, pH is a three-point calibration . Our pH is a five point calibration and is equipped with calibration powder (pH 4.00, pH 6.86, pH 9.18, pH 7.00, pH 0.01). You can calibrate to the accuracy of the measurement. 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. 5.High Precision Water Quality Tester: The high-precision algorithm chip and electrode of our digital water quality tester accurate and fast response. The green backlight LCD design ensures that you can read the measurement results under any conditions.
