Feature 1Wireless Connectivity: The pH meter connects to your phone or tablet in seconds and you can get all your readings in one view. It makes testing more accurate and convenient. 2Simpler and More Convenient Operation: Immerse the tester electrodes in water and wait a few seconds to get data on the LCD screen. No need to match colors one by one like test strips. 3Efficient and Fun Testing: One key storage of all measurement data, smart phone APP control, real time display, long term recording of measurement and calibration data, easy comparison and analysis, data synchronization, automatic and manual storage; Exce and print sharing export, annotations can be added to display the location, measurement value, time , date, note, location, etc. 4Good Performance: Measurement data lock, F and C temperature unit conversion, automatic temperature compensation, IP67 waterproof function 5Measurement and Calibration: Data synchronization, measurement upper limit setting (maximum and minimum), 2 groups of PH calibration (6.86/4.00/9.18 or 7.00/4.00/10.01).Item Type:PH MeterMaterial: ABSColor: As Pictures ShownWeight: Approx. 246g / 8.7ozPH Range: 0.00-14.00PHTemperature Range: 0.1C-60.0C , 32.1F-140.0FTemperature Resolution: 0.1C, 0.1FTemperature Accuracy: 0.5CPH Calibration: 6.86/4.00/9.18 or 7.00/4.00/10.01 (Two Optional Calibration Modes) You Can View the Calibration RecordReplaceable Electrodes: Drill Electrodes (3.3 KCL M Electrode Stock Solution)Temperature Compensation: 0.1C-60.0CEnvironment: 0.1C-80C, Relative Humidity: Max 90%Waterproof: IP67Battery: 4pcs 1.5V LR44 Button Battery (Not Included) Low Battery IndicatorBluetooth: Bluetooth 5.2, Support Mobile Phone ControlSave as Excel Sheet, Support PrintingData Storage: Can Store the Latest 1000 Data RecordsPiercing Electrode: Can Measure the PH Value of Soft Solids, such as Soil, Cheese, Meat, etc. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x PH Meter1 x Manual5 x Test PackageNote1. When analyzing the skin: There should be no sweat and dirt on the skin surface, but it should not be excessively cleaned (do not use cleaning products before the test), so as not to affect the measurement results. Wet the skin lightly with distilled water, gently press the flat electrode on the skin, and read after the measurement results are stable. When testing paper, fabric or leather: add 12 drops of distilled water to slightly moisten, then test directly.2. The product application will be updated from time to time.
