Model Number:Zerodis658hdg72nm Package Dimensions:26 x 11 x 6 cm Material:PLA_(Polylactic_Acid), PC_(Polycarbonate), PS_(Polystyrene), ABS_(Acrylonitrile_Butadiene_Styrene), PE_(Polyethylene) Special Features:Waterproof Feature: 1. Wireless 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. 2. Simpler 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. 3. Efficient 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. 4. Good Performance: Measurement data lock, F and C temperature unit conversion, automatic temperature compensation, IP67 waterproof function 5. Measurement 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).
