<p>Feature: 1.6-in-1 Meter Bluetooth-compatibility: Driven 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.</p> <p>2.Cloud Data Management System: Accurate real-time Bluetooth data mission, with clear measurement values. Allows you to save, manage, and share test data at your fingertips without worrying about data loss.</p> <p>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.</p> <p>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.</p> <p>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.</p> <p>Specification:</p> <p>PH value range: 0.1-14.0</p> <p>Resolution: 0.1ph</p> <p>Precision: 00B1 0.1ph</p> <p>Temperature range: 0.1 2103 - 8.0 2103 31.2 2109 - 176 2109</p> <p>Resolution: 0.1 2103\/0.1 2109</p> <p>Accuracy: 00B1 0.5 2103</p> <p>EC range: 0-1999us\/cm, 10.01-20.0mS\/cm, 2000-10000uS\/cm</p> <p>Resolution: 1uS\/cm 10uS\/cm 0.01mS\/cm</p> <p>Precision: 00B1 2% F.S.</p> <p>TDS range: 0-999ppm, 1000-9990ppt</p> <p>Resolution: 1ppm 10ppm</p> <p>Precision: 00B1 2% F.S.</p> <p>CL range: 0.1-4.0mg\/L</p> <p>Resolution: 0.1mg\/L</p> <p>ORP range: 00B1 999mv</p> <p>Resolution: 1mv</p> <p>Precision: 15mv</p> <p>Battery: 3 x AAA, excluding</p> <p>Display: LCD digital display</p> <p>Backlight: APP control</p> <p>Temperature</p>
